Default Diablo street tune VS Cow tune

This question is not meant to start any mud slinging...

I am asking for experienced opinions and advice regarding a street tune with data logging using a Diablo hand held through a guy on this forum VS a similar tune with Chuck Cow using his method.

I just finished the header Xpipe install on my 2010 base A6. It also has a K&N drop in filter and Corsa Xtremes.

I already have the Diablo Intune i3.

I'm just wondering if it's worth the extra money to sell the Diablo and go with a tune from Cow.

Thanks in advance.

You have the inTune i3 8245 Platinum version tool, right? That's the one you'd need in order to be able to do custom tuning. The regular inTune i3 8200 can not do custom tuning.

So as long as you have the inTune i3 8245 Platinum version tool, yes I can do a custom tune for you.

So a 2010 Vette, A6, headers, no cats/high-flow cats... no other mods...

Yes, I can definitely get you hooked up... I have tuned thousands of these cars and do them daily....

Please send me an email at -- diablo DOT help AT gmail DOT com -- with the year, model, engine of your GM vehicle, any mods done to it, what octane gas you use, which diablo tool you have, etc.. and I can send you a loooong email with info about the custom tuning, the process, etc.

Thanks!

Since you have already spent the money, I would do the Diablo tune. It takes some back and forth with the data logging I believe but Cow requires you to send him your ECM. Me personally, I was not willing to do that and wait. If you are local to Cow then might be a toss up if you can sell your unit for what you paid.

I do have the 8245 Platinum and I have emailed you already. I will be emailing you again this week about data logging. I just wanted to check into experienced opinions before moving forward.

Thanks

As we discussed on the phone, I can offer you features that nobody else offers.

Nobody benefits when these threads go south because each vendor is going to defend and promote their own product.

For the C6 Corvette, you won't find a better package and our tool is far more powerful than

than any other handheld tool.

Call any time if you need more clarification.

That's not correct. I have hundreds of ECMs here so that you almost never need to send yours.

I build an identical ECM on site and send it out so that for a short time you actually have TWO ECMs

and this way you're never without a car that runs and drives.

ECM swaps are only required for customers that get the CoW BOOSTER!

While we always advise customers to sell their existing tuner tools when they upgrade, we also recommend

you hold on to your original tool and tune until you receive your autocal. This way, if you have any reservations

we will save your original tunes so that they can be re-loaded at a later date even if the tool is sold off.

Once you have the ability to load theirs and then load ours for comparison, it will re-assure you that you made the

right decision to switch.

There is NOTHING like the CoW BOOSTER! in conjunction with our full tune package.

GUARANTEED!

Sounds good man... Thank you!

I actually had another guy this week email me too, to correct and fix his "cow" tune for his car that isn't running right since that tune was done, heh...

Have a good weekend man! We'll be in touch!

Yeah.... Know when to keep it in your pants with your unsolicited comments.

For most of the last 18 years I've removed hundreds of "diablo" tunes from customers cars who were woefully disappointed with Diablo products

and tuning.

Let's do our best to keep it friendly here.

But you had to one up him with '100s of customers' vs the one he mentioned? Then close with lets keep it friendly? I feel like I'm in a high school parking lot with the guy that has to get the last word...

This forum is full of happy Diablo customers.
If they are not pleased with their tunes, they don't seem to be posting here...

I am one happy CHUCK COW Customer. Chuck is the best of tuners. I have had SEVERAL from here, and I have been in the Corvette Business for 15 years. Chuck has made my Corvette SCREAM. His prices are excellent and his customer service is the best in the industry. This guy has gone WAY over and above the norm to help me out over the the years. I have sent him dozens of clients over the years, and not 1 has said anything except that Chuck is a tuning GOD. His AutoCal is definitely convenient.
Don't know what the pissing content is here, but I stand behind CHUCK COW TUNES FOREVER.
And to Chuck...... Thank you for making my Corvette so nasty. Acceleration issues?? Not a chance.

You might want to publish that information on your website. That is the reason I did not take advantage of your previous offer of a FREE booster. Sounds like that is something new and maybe an improvement of your process. A used the Diablo 93 tune and it was an improvement over my base tune until I added headers. I attempted to use them for a full tune but did not like the back and forth of data logging, so chose to have a full tune locally which I am very happy with now.

Chuck has done three Vettes now for me and my Dad. I couldn't be happier. Want to buy a used Dioblo tuner?

I was fortunate enough to stumble upon Chuck/CoW very early in 2007 when he was visiting Tampa to do C6 transmission and engine tunes at a local speed shop. I drove down from Panama City (an 800 mile round trip). His A6 tune transformed my Red into a far more driveble and ridiculously fun machine.

That was the beginning of a years long association. The following winter I drove up to another speed shop in Chicago where he tweaked my A6 tune, for free. In 2011 I drove Red to Chuck's shop in Ossining, NY to have him install an Edelbrock E-Force supercharger. That included a custom engine tune. I also bought an AutoCal "gadget" which allows us to update the engine and transmission tunes via files attached to e-mails, again for free. This past August I went back to Ossining with 140,000 miles on the clock for major renewals to my torque tube, torque converter, transmission, and rear end. Next month I'm returning to Ossining to have him perform a 100,000 mile maintenance on the supercharger installed in 2011.

Comparing Chuck's expert work on my Red over the years, I would have to say the Diablo and similar devices are what I'd call "panty-hose solutions". Once size fits all -- badly.

Default Cow Tune

I have been very happy with Chuck & his Cow tune. He is very professional and courteous in making the C7 perform at itís absolute best, You do not have to send the PCM to him, He sends the modified unit to you. His pricing & expertise & customer service is much better than most other vendors on the forum. Chuck is not happy with his tune until you are!! I would not even consider anyone other than Chuckís Cow tune after extensive research into custom tunes.

I certainly don't like seeing two vendors pitted against each other as I'm sure they both have their advocates. I've never seen a side-by-side review of different tuners so ultimately everyone needs to do their own research and pick one. I'm not even sure that such a review makes sense as there is so much more to this than raw numbers. In my case the primary goal was to improve the throttle response as I found the factory tuning to be quite conservative. It's just not right when you have a tuned Volvo V70R with better throttle response than your Corvette. After almost 20 years of driving tuned Volvos I was very familiar with the various trade-offs between peak numbers vs area under the curve, safe operating parameters across varied conditions vs tuning to the edge and taking risks, and enjoyable drivability vs irritating peaks and anomalies. I spoke to Chuck for a good long time and it was clear he knew what he was doing and his approach to tuning matched what I was looking for. He also provided the special focus on throttle response that I sought. I also looked at Chuck's LinkedIn profile - with his background in Computer Science there's a good chance he knows this stuff. So I went with the COW booster as well as the full blown tune. The results gave me throttle response that was just the way I liked it, the annoying skip shift was gone, and I got better power delivery with the full tune. Couldn't be happier. I then decided to install the Vararam intake. I got interested in this after seeing the ridiculously high intake temperatures on the C6 that were as high as my turbo car before installing the FMIC. I didn't realize that the tune would need to be redone with the intake, but Chuck is redoing the custom tune for no additional charge. I think we're pretty close to being done at this point. So far the intake+tune takes things to a new level and the car responds to it very nicely. Yes, the tuning process requires some back and forth and takes time, but the results are a very nice custom tune. For the amount of work and level of attention Chuck has to give to this, I found his prices to be more than fair. The IPD Motronic 7 "Stage I" canned tune on my V70R cost more and the tools you get with it aren't nearly as good as AutoCal. I have never tried the Diablo products so can't provide any useful comments there, but Mike seems to be a good guy as well, and a positive advocate of the CorvetteForum.

Default Tunning

I have a 2008 c7 automatic ...I had headers intake k&n but mostly stock on the motor were I purchased the diablo sport runner ...were it didnít do much change to the trans it would still shift slow and lazy normal driving and the worst was even with the tune it would surge a little on the rpms at idile....so I decide to sell the diablo runner and give chuck cow a try ....I am telling you the car feels just like a whole diffrent car when shifting driving and no more surging itís not another tune meaning like the diablo tune a canned tune if it works on one car it works on all to me thatís not true all cars react diffrent I would give chuck cow a try truly recommend it he puts a lot of time and effort what he does awsome runner you wonít be disappointed

There's no bashing here, it wasn't intended...

the thing here is, you can't compare a handheld preset canned tune, to a custom tune...

HOWEVER, custom tuning can be done with diablo's tools! And a custom tune that's done, using the diablo tool as a loading device, is on par with a custom tune done from others... many people don't realize that custom tuning can be done using a diablo tool... The diablosport custom tuning software is like hptuners, efilive software that others use for creating custom tune files for things such as the efilive Autocal tool.. the autocal tool is a tune loader, that loads custom tune files...

If you get custom tuning done and you have a diablosport handheld tool, the diablo tool becomes a tune loader at that poing, to load a custom tune file that was created with their custom tuning software...

And a custom tune done for it will always be better than just the preset canned tunes that come on the tool... I think a lot of people miss or misunderstand that point, or don't realize that custom tuning can be done for a diablo tool...

Custom tuning can be done for diablo tools, just like it can be done using an efilive Autocal tool, with the tuning software.... you are not limited to just the preset canned tunes that come on the diablo tool itself...

That's why I have people do real-world driving data logs for me when I do their custom tunes.. so I can see exactly what the car is doing, etc while driving it in real-world driving conditions.. . you don't drive your car on a dyno, heh.. that's the benefit of doing real-world driving data logs, so the tune can be adjusted/tweaked appropriately....

Just the same..... I am not limited to the regular HPT, EFI LIVE, or Diablo tune parameters and I'll often create and use my own custom stuff that is not

available to other tuners using regular tools.

Additionally, while not everyone needs the full capabilities of the AutoCal device, for those rare occasions where you're in the middle of nowhere and

your car develops problems.... You'll be glad you got your AutoCal from Chuck CoW..... This tool has plenty of features that only professional tuner tools have

and it will let me remotely do stuff even some of the pro tools can't..... and that's what makes my tunes different from the others.

I wouldn't dare mess with someone's car remotely without my AutoCals.
