He suggested having a tuner tune it, but said that it wasn't needed. He said it would be fine without the tuning. What do you folks think? I have no idea where a tuner would be anywhere near me. Maybe S&P? I haven't checked yet. Do these computers "Learn"? I don't even have the motor yet, I'm just making plans. I am getting the accessories, uncut harness, computer, 4L60, TAC, pedal, etc. out of an 05' Suburban. I'm not going to race it. My girls will be driving it to school, and they have to impress...

THANKS!

That sounds like a Comp Cams xr265hr cam. If so, I've used it in a 5.3. Stock idle and definite seat of the pants improvement. I eventually made 444/485 HP/TQ to the wheels but that's with 10 PSI boost
