What happens with the cutom tune if you take your truck in for warranty repair and they re flash the computer?

dunno. i don't know why gm would want to flash your pcm anyway. unless there are updates like dodge is doing. if that is the case, they had best let the customer know. otherwise, to me, i would be irate if they touched my pcm without letting me know.

Oh and forgot to mention, being a rcsb 4.8l 5spd also go ahead and get ready to do a t56 swap. If you don't watch yourself with that 5spd it won't last long. I've got 52k on mine but have been babying it for the last 10-20k. The nv3500 is $hit.
