Well after being down for a while, I finally have my truck running again. Wow ! AND IT FEELS GREAT TO DRIVE THE SOB!

I installed a 4l80E and a PI 3200 stall.

Went out last night and started on tuning it.
I have 2 problems:

# 1 -- I noticed that when I get on it my IAT start going up then back down. Then I come to a stop and they rapidly start going back up. It was about 75 degs outside. While running the iats would drop to about 95 and then when i would stop they would go up to 125. The truck wasnt even heat soaked. Could I have a bad MAF? Or what else could it be.

# 2 -- If I try to launch from idle the truck hesitates or even pops a little. If I rev it up a little then back to idle then launch, it works fine. If am driving and come to a complete stop then punch it form idle it wil also hesitate. I checked all my sensors plugs and it worked fine. The only thing I did was change the oil psi sending unit. ( which of course I had to remove the Intake) Any clues at what might be causing this? I think it started doing it after I put in the 4l80
Or what else can it be? Could it be the MAF also?

Thanks
