I have a fmic, midpipe w/high flow cat, motor mounts for main power mods. I made sure I had at least a boost gauge, colder plugs, and a stronger BOV before upping boost.
It took under 2 hours may have been faster but vacuum lines always confuse the **** out of me and the kick plate is a b**** to get back on. Other than that it is basiclly plug and play and can be done alone.
Even on just map a with stock boost is worth it I think, turn on the boost and map b and it is a mean car. It runs smoother and a hell a lot funner to drive. One thing that I noticed is on stock boost it now spikes around 7psi opposed to 6 when it was stock and with boost up it spikes around 14psi. It's better on all levels it runs like a whole other car a night and day difference. Easiest and very effective mod for engine management.
