before i buy all this stuff i want some advise.
- gen v supercharger
-3.0 and 2.8 modular pulley system pulleys from zzp
-stage 2 intercooler with l32 lower intake manifold and modified fuel rails
-60# injectors
-not really sure what throttle body, leaning towards northstar but do not know what MAF sensor i need
-1.9 roller rockers
-already have headers
-What pcm should i get? and what brand?
I do have a question, do i need to change the valve springs or pushrods?
Any suggestions is much appreciated.:th_thumb-up:
 


I'd get a 3.2 pulley swap the valve springs. Where are you in Ohio? If you're close by I can tune it
 
For a setup like that, a canned tune is gonna suck the D...hard.

Rockers are boring, but if you don't want to cam it, I understand.

As for the GenV and LIM, I've actually got a GenV and matching ported LIM to go with it...both in great shape. Shoot me a PM if you want it on the cheap.

TB, I'd go ported stocker. Especially if you go rockers, it's gonna flow just fine. If you do anything over 1.80:1 ratio rockers and 6k RPM shift points, you'll want to change the springs, yes. Which means probably going with LS6's. Easy, they work, and they're cheap. Tried and true. Pushrods? Meh. That's up to you. I got Intense O/R pushrods when I built my motor.
