so i've been looking at some parts for my car and i found this website that said they installed certain bolt-ons and then dyno'd the car and it said that the underdrive pulley's made 14 hp at the wheels and a hand held tuner site said that on a stock motor the sct tuner made 20+ hp and even more with other mods on the 93 octane tune....so my question is that if i add these 2 parts is it going to increase my hp about 30-40 at the wheels because i find this hard to believe but if so then im all for it...i just dont wanna spend 200 on pulley's and 400 on a tuner and then not get the results that they say...and do you think i would feel noticable gains from this....thanks for the input guys and gals

I'd say more like 20 at the wheels.
I agree with about 15-20rwhp gain. Advertisements like that always tend to exaggerate a little bit. With tune, cai and exhaust i gained about 20rwhp.

I believe also that underdrive pulleys are only good for around 10HP more.

You will feel a gain from them but when you dyno your car with these mods, don't expect a huge gain. I say 10-15rwhp that the above gents said.
