Celica Forums General Discussion Exterior Dyno hp gains from AEM underdrive pulley for 01 Celica GTS?

I currently have an AEM alternator underdrive pulley for my 2001 Celica GTS and I'd like to know what the Dyo hp gains are just for installing this part? Right now all I have is a Injen Cold air intake and a magnaflow cat-back exhaust. The reason why I'm asking this question is because I want to know if it's worth installing or not.

the pulley will only add 1-2 hp, but you get better throttle responce. So is it's up to you really if that 1-2 hp gain is worth it. IMO I'd install it, you gotta squeeze every hp you can get

its worth installing

yeah i want them
