i was wanting to get a mail order tune but im worried thats gonna void my extended warranty replacing the pcm. what handheld tuner would u guys recommend?

 

Contact of Jesse at Wait4Me Performance. The last time I heard he charged only $75 for a tune, you can also get another PCM from him. Keep you orginal pcm when you have to take it back to the dealer and have the tune for the rest of the time.

 

I may be wrong on this, but I think I read somewhere that unless the dealer can prove that a ceratin mod caused the problem(if you were to have one), they can't void the warranty just because it's on the vehicle..

 

They can blame it on anything they want..lol...i dont chance it...mine goes in tomorrow for warranty work..and the stock PCM is going in for that....JUST in case

 

Mail order tune from www.nelsonperformance.com
Allen Nelson is one of the best tuners out there for GM vehicles!!!
All re-tunes are free for the vehicle he sends the tune out for.
After you do a mod, then a free re-tune is in order.
Tell him your mods, how you will be primarily using your truck, and what octane fuel you will be using, and he will set it up for the most performance you can get out of your engine/ tranny & your mods.
The 93oct tune will of course be the best tuning you can get.

with the nelson tune do i get to keep my old pcm? that way ill hav it to plug in when i go to the dealership

 

Yes you can keep it, but I belive he will charge you a little for the core.
Just e-mail or call him.
I just catch him when he comes down to Houston and have him just hook up his laptop and do his magic.
My PCM has actually never been taken out.
But others do it all of the time. Some vouch to keep their original PCM and others just wait for him to send out a Nelson tuned PCM and then send their original PCM back to him.
Either way, he can always send you back a factory programmed PCM.
