Thread: PCM and Pulley upgrade

You'll be fine getting just the PCM and intake. DO NOT mess with pulley sizes until AFTER you have a sufficient amount of exhaust mods, which you will be able to determine by scanning. Since our cars are getting older and KR is becoming more of a problem I would suggest getting header's before you start dropping pulley sizes.

Aftermarket PCM's just have a generic tune, they aren't really mod specific. If you want a tune that is set up specifically for your car and the mods you have, then you're going to have to get a tuner. But to kinda answer your question if you get a pcm, you'll be fine with adding mods later, no need to change anything. Tuning it would be better, but for most cases it isn't really necessary.
