I made 13whp and about the same tq more with a fast 90 I ported over my ls6 intake that I ported. It got close to 20~ for each under curve. Is it worth it??? Depends on how fast you want to go I guess. if you happy where you are then no. If you like squeezing all the power you can out of a combo then yes. Engines seem to run best when they're really efficient.....the fast intake adds to that. I picked up about 2mph with the switch. A definite sop improvement and a tune is a must with it imo.

Unbolt the ls6 and bolt-on the fast and I lost little power under the curve......a little tuning and I gained that back and then some.

Agreed im running a fast 90 tbody and fast 92 intake bolted on from ls1 intake and even without tuning def feel difference. I looked ariund for a long time and found my jntake that came with 42lb injectors and bbk fuel rails for 800.. just have to keep eyes open and hunt!!
