Factory LS6 intake and a factory P/P throttle body is more than enough. Fast 90/90 on a stock motor will probably lose power.

yah i think you will propably lose power on low to mid rpm,i have SAdesaign book and they did talk about it, it make very good power on high rpm but lose power on low mid with stock engine but if u planing cam and heads package it will help u get a massive power,good luck with ur tuning

Which is better then? A head/cam car with the LS6 intake with a P&P TB or the head/cam car with 90/90 set up? I have an A4 and want 450 at the rear wheels before a shot of spray. I was thinking of getting the Fast intake just to have the ease of the direct port spray. Any help?

obviously u pay what you get. ur not going to lose power with a 90/90 under any circumstances on an LS1. you will really see the gains with heads/cam

actualy there is a lot to loose with the fast 90/90, ive seen them give tuning issues, you can hurt the bottoms of them real easily, you loose low and mid range etc

dont even bother putting a 90/90 on a stock motor, the only benifits it has is that if you have a nitrous backfire itll destroy the bottom of the intake as a sacrafical pannel. but then you have to pull the intake and replace the bottom. might as well take your chances with an LS6 intake (nitrous backfires that destroy the intake are pretty rare) and if it blows up buy another one.

LS6 intake, stock throttle body > overpriced FAST junk

What you are looking at is really overkill on a stock motor. It would be like putting two inch headers on a stock motor. Just too much dude. Think of it this way....kind of like polishing a

Actually, we have done a few complete bolt on LS1s and made power with the 90/90 combo.

As for tuning issues, anything can cause "issues" it boils down to how good the person tuning your vehicle is.
