The 102 manifold properly ported is a small improvement over the previous properly ported 90/92......then the fit issue's with 102!
A 102 manifold out of the box works very well, gains by porting are not as dramatic as the 90/92.....then there is fit issue
My C6 I tried the ported LS2, that was very disappointing, then a ported Fast 92, very good. Gains with the ported Fast 90 on the LS2 are very near the same as long tubes. SOTP is what the dyno does not measure, that is very good as well.

i've got an LS2 90mm on my 2000 LS1 & lost a good bit of low-end, light-throttle response... but then again, that's more due to the TVS2300 i have to move air through

You can't fix the LS2 manifold, been there done that & tried it. A Fast manifold ported by Tony is very good hp/$.

Dammit!
FAST needs to come out with something. LS6 intake won't cut it. 102, well that's a no..

Just fitment problems. Shim the cradle. Maybe other things. I havnt looked too into. But just with that, not many people wanna go thru that hassle. I think they really need to come out with a FAST 90. This will also eliminate the huge debate of 102's being to big for 346's

I don't believe it is but there's any any people that do. Hell I bought a FAST 92 and a friend kept telling me that was too big for a 346. Don't believe him though lol
