I'm running 12.1 @ 118 thru the LS6 now, plenty good for me. I don't see a reason to spend 1500 to bust into the 11's (which if my 60 ft was down I would be anyway). As mentioned, if you need that extra kick....

haha-you really think a fast 90 will loose 20 tq at 3000-a no
The fast is an exponential mod. The more mods you do the more it will shine over the ls6. If you keep it stock or mostly stock go with the ls6, if you plan to go h/c go with the fast. Dont buy the ls6 just to swap it out for the fast, keep the stock intake if your just gonna do that

From the mods listed in your sig, I would have to say the ls6 intake would work fine for you. Once you get a cam and some heads, or are planning on getting them installed the same time as the intake, then I would get the FAST 90. Otherwise, you won't see much benefit from it IMO. I would save that money and put it towards the cam fund. $600-700 is about 1/2 or so what it takes to do a proper cam swap and a tune. That would be a heck of a lot more beneficial than just a plain ole FAST 90...
hell i went a head and got a fast 90 and nick williams new black 90mm TB... and had intake painted and looks sweet...
planing on a cam later down the road but never seen a bolt-on only with a 90/90 set up so figured id see what would happen even though everyone has said its not really going to pick up the power as if it had heads and a health cam
but havent put it on yet... manly waiting for the weather to get in 40'es again so the #'s will look best on the dyno when it gets re-tuned by nick williams
