well i have seen decent gains from them. probably 6 to 8 hp on a stock car. 10 on a bolt on car and 15+ on a HC car. I dont really go by dyno numbers as i believe track numbers are the best indicator. Just doing the tb sway on my ms3 cam only car with the ls1 intake i gained .2 and 1.5mph in the quarter. I havent been to the track with the ls6 intake yet. I went from 11.92 to 11.71 with stock ls1 intake ect. back to back runs same 60ft's ect. On cars with an exhaust and lid gain at least .1 and 1 mph in the quarter, ran back to back as well. As well as an increase in throttle response.

In my case, the throttle was much more responsive, but I didn't gain anything at the track. Still, it was well worth it. The improvement in driveability was awesome.
