Want a tune, but

Recommended Posts

Really want to do a tune 0n my 2009 Colorado 5.3, but am a little worried about the warranty thing. I plan on having it done professionally done by a highly regarded mech. in our area at a tune of $415.00 no pun intended. I have herd great things about this mod performance wise. In your judgment, are the possibilities of having any problems pretty small.

what tuning software does he use? if its EFI Live, you can get their FlashScan V2 module so that you can install the stock tune before going to the dealer. same if he uses SCT software, you can get their X3 Power FLash programmer. if he runs HPTuners, then your SOL unless you have your own laptop and want to buy the tuning software so you can revert back to stock when you want. other than that you can just get a power programmer, like diablosport, superchips or hypertech, so that you can go back to stock when needed.

The last 4 trucks I've owned got tunes and none had a single engine issue. With that said, the possiblity is there and I was willing to take the risk. You could keep your stock PCM and install a new one with the custom tune. That way you have the option to go back to a stock tune.

 

If your that worried, I'd not do it till the warranty expires :thumbs:

I just had Justin (BlackBear) tune my Sierra Denali using the AutoCal. Awesome way to go. You get your stock files and can load them back to your truck at any time. If you are bringing your vehicle in for service, and are concered about warranty issues, just flash your stock files back in! Very quick & easy.

The mechanic utilizes a HP tuner and states that he can reset the tuner back to stock in the event the truck needs to go to the dealer with engine issues. Once the engine is tuned, can it easily be put back to stock and then put back to tuned.

But can YOU return it back to stock on your own, or do you have to have your mechanic do it? Blackbear with autocal is really the better way to go IMHO. Only a few dollars more and I'd be willing to bet a better tune to boot. Justin really knows his tuning. He's da man! :)

Get the Autocal through Blackbear performance..... Justin is the man and you can control it all at your leisure in regards to putting it back to stock, then back to the tune. Only way to go IMHO :thumbs:
