OK I'm tired of looking at 350Z tail lights, so it's time to step things up. Trying to keep my engine stock, but looking to build some extra pressure in those pistons.
I am currently looking at several choices for plugging in a piggy back into my cars system. just trying to figure out who out there has the best deals. my budget is $2,000 realistically since I need cash for injectors, fuel pump, press. reg, and a few other parts. If pressed I can go $3,000.

So what's out there that might work well enough to retard timing and adjust fuel pressure, and offer some Aux ports?
