If I were you I would re-gear and add meth. With 35's on the stock gears and converter, that pro has got to be sluggish. Meth will help your IAT's more than any intercooler swap, and be safer as well.

not sure on hp numbers and havent been to the track since zippy tuned it but we have a awd dyno opening here in like a month , cant wait...

Yeah looking at doing 4.10 gears with a posi. Also plan on doing the Meth and 4l80e with around a 3000 stall. After that stuff gets done then looking at a cam and head work.

Sounds good yeah haven't seen one around me so sure there hard to come by keep me posted!

just to warn you the 80e will suck some power from the bottom of first gear but the first gear is long and feels awesome from like a 30 mph drop, and the first to second gear shift is wicked. i put a hd-2 shift kit in it and put it on the medium setting when installed. i have a 3200 stall on it witch is good but wish i would have gone bigger 3600+ .

Yeah I have heard it will take away power and yes wanted to do the shift kit. Thought that would be really high stall for daily street driving? I've never drove a vehicle with a high stall so Idk what to expect

I have a PI 3600 on mine, and it didn't feel bad dd everyday to work.

Alright wasn't sure thanks! What's the most boost y'all have run on a 5.3?

i dd my truck and its not bad at all. it wont stall to 3200 unless your WOT .when i take off from a light it only goes up to like 2200 or so cant really even tell its there.

i was running 11# till i put my cam in and now i only see 8#s with a 3.4 pulley on my p1 but i have a 6.0.
