If you want to see Diablew's history as an enthusiast gone professional, all you have to do is Google his username 06MonteSS. He's obviously not ashamed of what he's ever said or questions he's asked. The Internet is an amazing thing, but via the tuning forums you can follow his growth & experience as tuner for yourself. Now how would you fair under that kind of scrutiny at everyone's fingertips???
I've followed his threads before he even bought the CMR software. His tuning knowledge & attention to individual needs is excellent. Am I a "Fan Boy", sure, just as anyone else who has followed his threads over the years. He knows what he's doing, but please don't take my word for it, read it for yourself, It's literally a ~10 year resume online, Google is your friend.

You did headers filter and tune all at once? Or you picked up that much from the tune alone?

and I'm not confident that when cobra did those dyno pulls, swapping tunes back and forth, that he even had the custom tune installed correctly, or at all.. because every time I had sent him a custom tune file, he was never able to get it installed correctly the first time.. would take him a few tries to finally do it right... so am I confident that he got it right the very first time when swapping tunes to do the dyno pulls and that my custom tune was actually loaded during the pull? no...

See, I told you that you were going to be unhappy with me. I’m sorry the numbers worked out against you, but people wanted some data about your tunes. Now you have gone defensive on me with words that I cannot figure out what you’re saying. I’m not going down that rabbit hole. The numbers are the numbers, good or bad.
By the way, my C7 went on the dyno with your tune in it. It was the first pull, no heat soak or any other excuse you can come up with. I still love ya, man….

Heres the thing. My local shop (livernois motorsport) with a custom tuned C7 were able to make 30WHP over stock. I trust them, and therefore i know its possible to get this gains.
for now i will want and see.

30 is a very high number on tune alone...

my point is that at least they will show your car on the dyno stock, then right aright tune it and you see the gains right in person.
these diablo tunes, its crazy how much lack of data we have. everyone bases there gains off feelings of the engine. its crazy.

Lew,
I know you’re going to hate me, this but is the God’s awful truth. When you decided not to help me tuning for E85, saying you never used it and never will use it, I had no alternative but to go with someone else. This time around I chose to tune on a dyno instead email tuning. To make a long story short we first did dynos on the OEM tune from the factory vs the last tune you did for me. The results were your tune was 413.66hp/411.25tq and the stock tune was 417.37hp/418.40tq. Then the tuner retuned with his changes and got 424.26hp/424.96tq. I guess all email tunes are not equal.
I’m not trying to “dis” you, I just wanted to tell my story and what I have found out about email tuning for the forum. I too (using the seat of the pants test) thought I was getting somewhere. You don’t really know what you have until you put it on a dyno. There was a significant difference between your tune and theirs (seat of the pants and otherwise). I guess this your first "C7-specific users report...".
By the way, I picked up another 23hp/20tq with E85 (actually E65 for the test) and an E85 tune.

His tune could have made 10 less rwtq and rwhp and still have been 2-3 tenths faster in the 1/4 mile easily. You never said if there was knock on the high end of the pull.
Most importantly, you never said what the power looked like throughout the whole curve??
Unless your trying to make your car into a dynoqueen then we need more info about the whole pull, not just the peak...

Im not really sure how this post is fair to Lew. I don't know Lew, never talked to him in my life

Here are the dyno sheets. I hope this helps.
This is Diablew vs Stock

Look, enough is enough. This is what was given to me at the shop. I don’t know from 002, 003 or any other number. My car came into the shop, went on the dyno with Lew’s tune in it, a pull was made, the stock tune was loaded, another pull was made with the stock tune, and then the other pulls were made with PowerFab’s tunes.
If you think this is an assassination on Lew’s reputation you need to pull your head out of your ***. Yeah, I’m going to take the time to doctor up a document just so I can dump on a guy who I like and respect. Maybe in time (I’m sure) he would have fixed it, but I wanted E85 and Lew didn’t want to do it so I had to go another way.
When Lew was lying in a bed in the hospital very ill I made a donation to him to help with his huge bill. Ask him, he’ll tell you. Now, what sinister thing can you make out of that?

Usually dynos record the runs in order and you mentioned you pulled Lew's first so I asked, that's all.
I'm just looking for facts, not trying to make anybody out to be bad or good. You sound awfully defensive for a guy "just telling it like it is".

I would always ask, were you happy with the tune before the dyno disappointed you?
I have seen so many people love their car and how it runs until some dyno spits out some number that makes them think the car or tune is not working right...its quite the phenomenon

Everyone agrees that the Diablo canned and diablew tune put a smile on your face.

But thats really all that counts!!!!!
You cant feel 5-10 rwhp on a 400 rwhp car....no way.
But if you can tell the car is more responsive and puts a smile on your face bigger than it did previously, then the tune has done exactly what it was supposed to do!!
Its about SOOOO much more than meaningless dyno numbers, dynos dont measure TM, dont measure shift feel, dont measure throttle response or traction, they tell you such a minimal part of the whole story. Have I mentioned I hate dynos?
Thanks

What about the fastest bolt on GS on this site that used our canned tune to run 11's at over 122 MPH, surely the tune was working well and making power, or everyone would be running those times
Reducing TM which causes the PCM to close the throttle and/or pull timing during shifts will always make a car faster, cant think of a case where it wouldn't, yet that will never show on a dyno, and there are all of ZERO track results being shared, which is all that should matter in this conversation
You are more than entitled to your thoughts on the subject, but I feel you are over simplifying it.
Thanks
