I heard a good combo for gains are the brenspeed delete plates and underdrive pulleys..
good for about 12-15hp(??),not bad for about $280

I know this is going to make me sound stupid but I am going to ask anyway. What are delete plates?

They are worth it, but you're not going to notice a huge difference. I installed mine with delete plates so I noticed a somewhat decent gain.

Hindsight 20/20, I probably wouldn't do them again. I had Steeda install my pullies and really didn't notice a seat of the pants difference. I will say it does seem to idle a bit smoother though. When I installed the UDP I had Steeda CAI & SCT Tune only.

Every little bit helps....most guys get between 6 and 10 at the wheels with them. I've had mine on for over two years without any ill side effects.

It depends on your future goals.. do you ever want tosuper chargerit? if yes.. then I wouldn't get them. You can't use them with any super charger.. same with the cmcv deletes..(I believe) if you want to just do every last bolt on and stay n/a then go for it..

If you do get one, go with Steeda. They make the best quality UDP of all. It's the only UDP I would trust on my car to be honest. I plan on getting one since I'm staying NA with this car.
