Better off with an LS6, especially if it is a street driven regularly car.

Stick with the LS6, dont waste your money, and then when you have enough get the fast. LS6 flows well anyway...

You could always have TPIS modify your existing LS-6 intake with a 90mm for a few hundred bucks
It will only be a few hp shy of the Fast 90 but alot more than the stock LS-6 in certain applications but cost 100's less..

Seeing that you have a 99 car unless you have a LS-6 Intake the gains wouldnt be as great..
But if you have an LS-6 Intake the gains are pretty close to a Fast 90 without spending all of the money..
I have been using it on my car for the last 1 1/2 Yrs
The Benefits
LS-6 vs TPIS vs Weiand vs Fast 90 ect..

Cool I have a 408 stroker almost finished just waiting on cylinder heads, Intake and some tri-y headers for it..
If you are on a budget the TPIS Modified LS-6 Intake would definitely get you some gains compared to what you have now..
All they do is cut the stock snout off of the LS-6 Intake then attach a 90MM opening snout to it for use with their 90mm throttle body..
But for a 408 I would go with the Fast 90..

In the October Issue of Hot Rod magazine htey did a write up on 6.0 iron block and intake manifolds and the fast 90 compared to the stock LS6 intake was only a 6.8 rwhp differance. So since I have an LS6 intake, I dont really want to pay $900 to $1200 dollars for the new setup...

LMAO!!! Don't sell yourself short. I have H&C, and just by changing from a stock LS6 manifold and TB to a tricked out FAST 90 w/ 90mm Nick Williams TB, 42 LB injectors, and going back to a stock MAF from that POS 85mm Granitelli I picked up 51.03 RWHP and 27.39 RWTQ. And I can tell a huge difference. I only thought I had traction issues before...

How much did all that cost you? the whole point I was saying is that I didn't want to have to spend $$$ on a intake (fast 90)when I have no idea of what your engine is, and If I am going to buy an intake system I am not going to run fast, I have a 408 stroker engine that is 11.1 compression and I am going to get a sheetmetal intake system through spectrum 5 racing or through john beck and then i will laugh at the fast 90, twice the air flow and at 530 rwhp I dont feel to bad with my setup expesially if my intake is so bad. there is no point buying th fast for me when it would still limit me...
