exhaust usually always helps a turboed car noticeably, maybe get the needswings sp? e-cutout? or you can run that side exit and belch flames like my boys acr. haha you get get turbo toys i always thought that was pretty sweet if i ever go boost in my first gen with a srt swap im gonna try to make that fit and work in my ride and look stock. just some ideas

Anything over 18psi you're just blowing hot air, and it won't hold it to redline anyway. Crank it too high and the PCM will pull timing. I don't like using a boost controller myself, I ended up with Stage 2 because I hate the PTB you get with an MBC on these cars. But that was before you could flash the PCM.

You don't need the fuel pump, but if you have one it won't hurt. What injectors are on there, the original 03's or has it been updated to the stage 1/ 04 and later injectors?
