Just got through installing cranes powermax tuner.This thing is nice,no bog between shifts pulls all the way through the gears,shift alot better,although 1-2 shift is alittle soft,plus i can't even tell the tourque managment is there.I used to have the hpp3 installed and this blows it away.I'm sure a tune like nelsons or westers would be better I don't know i've never been in a truck with either of these tune installed but i'm extemely satisfied with this tune.Just thought I'd let you all know about this and if anybody is looking for a hpp3 for on 03 5.3ltr 100.00 and it's yours

Do you still have the hpp3? Can u send me some info on the hpp3. How to pay? I have a 2003 Z71 5.3L (aperry20@comcast.net)

Hey aperry20 I sent you a p.m.
