How much hp and tq would a JWT ecu give my 97 SE 5spd. All i have is the underdrive pulley. CAI to come soon. Do you think it is worth all the money.

 

There have been about 5 threads in the last week anwsering all your questions. Why don't you try looking there.

 

Out of all the mods you can do, why'd ya get an UDP as the first.. it's basically the least effective thing you can possibly do. Personally, I'd get a y-pipe first, pretty similar gains in terms of hp and like 1/3 the price.
