I have had Chuck's tune sense 2007 on my first C6 and a2011 HHR AND MY DEALER know that have it done and have never rejected warranty. He's going to tune my C7 as soon a I see him. With that said Chuck Cow is going to be a to Corvette Expo on March 21-22 in Sevierville Tn and is going to my dealer to tune a Camaro for them. Have a great day

 

Thank you Charlie. This is gonna be a really good time.

Really looking forward to it.

I hear that the Southern Fellas are good bit more relaxed than up here.

See you soon!

Even if a tuner has a dyno it means little to nothing. There are so many subtle ways to influence a dyno run that the results are useless unless you take it for a before and after run at a dyno not associated with the tuner. As mentioned in a high performance non blown engine there is almost never a safe way for a tuner to make more power.

 

If you buy his mail order tuning service and an AutoCal then you get free re-tunes. Been there done that and on my second car with Chuck.

It's simple really and works quite well. I data log and e-mail Chuck the file. He looks over the data log and makes adjustments to the tune. He e-mails me the new tune. I load it into the car and make another data log...I send it to him. He re-tunes the car again....

I even changed heads, cam, exhaust, intake, converter, etc. Again I send Chuck a new data log and he re-tines the car via making changes to the tune file and e-mailing it back to me.

It's part of the tuning service. It is a back and forth process that takes a little time but is well worth it.

And for me Chuck has gone above and beyond even fixing technical issues that were not his fault.

But if you drive in there with a car and have Chuck run the car up on the lift, install a wide band, hook everything up, take the car out for testing and tuning and get the car all tweaked out, (lots of labor) your tune is done. If you go change the air cleaner to a Varram or something you can't just drive in there and expect him to go through that whole process again for free. No one does that. You can't go put headers on the car then bring it back in and expect it re-tuned for free.

If you bring your car in for headers to be installed and Chuck's shop does the work then he'll re-tune the car for you.

If you want the free re-tune deal then it's part of the mail order tuning service.

 

Your factory warranty is voided if he altered the computer settings.

Welcome to the forum Dyno Dave, see you just joined and only have 5 posts and they are both only in Chuck COW's related threads.......again welcome to the forum.

 

I have heard if you bring your car in for service and they happen to see any tables in the tuning messed with INSTANT VOID OF WARRANTY . Can anyone elaberate on this.

 

YES... THANK YOU! We caught ANOTHER one....

Thank you for exposing the fraud.

I've been bashed 1,000 times by people who just join the forum to hassle me.

Actually, we caught one dick with over 25 different user names/e-mails all belonging to the same person.

His sole purpose was bashing me on the forums.

LOSER.

never seen them look at the tune during service before or couldn't think of a reason they would.

 

[QUOTE=corvettor;1586409223]They can only void the warranty if the mod relates to the problem. They can't refuse to replace your radio because you changed the suspension. Now if you modify something to make more power they can void your power train warranty.
The only way to make more power and it's going to be very small in a modern non blown high performance engine is to eat into the detonation and other margins built into the factory tune. Might work for you until you get a tank of bad gas. Most tunes due nothing other then change throttle response to make the car feel faster. Between that and everyone's desire to see a result for their cash people always think a car is faster after a tune. Ask Malibu boats how their boat tune worked out on Corvette motors a few years back.

 

Anything that effects the power train . . . . . .

 

[QUOTE=Sailfun;1586409505]Sir this just isn't true so I find the need to state another, factual, account.

Thousands of Vette owners, myself included, achieve significant (30-40 rwhp and ½ a second in the quarter mile), dyno and track documented gains from tuning, and have very reliable machines for years and miles.

My c6 has been tuned for 8 years, 76,000 daily driver miles, and seen serious drag strip duty (494 passes launching at 6k like in my signature).

Tuning has a significant effect and absolutely can be done safely. If you add modifications such as headers or a super charger, you must have a tune. The factory tune cannot handle these modifications (it can handle headers but it's not optimal, you are leaving performance on the table, and you will get a CEL for cat inefficiency).

Tuning can reduce some of the safety features built into the factory tune, and if the tuner doesn't know what they are doing they can introduce dangerous settings that will blow up the engine. But a tuner that does that doesn't remain tuner for long. Chuck COW has stood the test of time. He could post stories about how owners abused their cars and blew up engines, but he doesn't do that.

I do believe the factory is correct in denying engine related claims that were caused by an improper tune. Thus when you tune you should choose a tuner with a lot of experience and a long successful track record.

 

 

Andrew, I think your quote inherited the goof up from Joe_G's quote. I'm sorry I missed the tune. Now that I'm out of warranty I would have liked to have a COW tune.

 

oops fixed

 

No sweat my friend!

From the looks of things you should be seeing me at VARARAM and Andrew's place again BEFORE the year is out!

Stay TUNED and watch the forum for details.
