Chipping out a Denali without voiding warranty?

[timjohnson22]

I use a diablo sport predator tuner and I have a lot more power and save on gas. The diablosport predator tuner saves your factory program so when you take it to the dealership for work just download your factory program back into the truck. The truck remembers your last 5 starts. Just start the truck 5 time after you reinstall the factory setting and the diablosport predator tuner tunes are wiped out.

You just answered my last question...thanks Tim.

No handhelds can tune both the ECM and TCM on 09+ GMs.

I just installed the SuperChips tuner #2865 and so far the results are good. I have noticed an increase in throttle response and acceleration. But, I also installed the "performance tune" which requires 91 octane. Dont have 91 here in Milwaukee only 93. Shifts are a little more firm as well.

Have not driven enough to confirm mileage gains or losses. I have been on the gas a bit since installing so my mileage will be skewed for a while.

it also has a fuel saver mode, which, i doubt i will try but hope it works if I do!

So far, pretty happy with the product.

What about the upcoming AutoCal? Justin indicated to me that it will tune the TCM as well...

I just installed the Diablo...



Wow.

Yes, the AutoCal will be able to tune all TCMs. EFILive V2 can tune all TCMs as well (but I don't really consider that a handheld).

Wow.

just think, with a custom tune it woulda been more like "wwwwwwwwwwoooooooowwwwwwwwwwwwwwwwweeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee!"

Have a stock 2007 Yukon Denali, I'd like to get a tuner of some kind in which I can adjust for performance, towing, or gas mileage. Will this void the factory warranty? Is there any way around thins?

I have a BlackBear tuned, factory ECM for sale! Bought and tuned my them.

This is for an 07 denali, but you can have it reflashed by BB as well.


If anyones interested, I sold my denali, so give me a good offer and ill ship from San Diego, CA.

Night and Day better than stock ECM.

I wonder how much different than my predator tune?
