You gain a little hp, lots of midrange torque, and it really makes it pull smooth. Only downside is gas will be a little more expensive. It only works for a 5 speed though. I've noticed my rev limiter is now at 7000 rpms. Only had the car a few weeks before I put it in, so i cant be sure if they are all like that. Everyone who gets it agrees it is the best mod you can do for the price, or even 2-3 times the price!
