If you are going to put a FPR and bump up the pressure, be sure to put a new Walbro intank pump with it. Last thing you need is the stock D series pump (as for all you know, the pump has not been upgraded) to shit itself not long after you put on the FPR.

Personally, I would hunt down a 4.7 or 4.9 final drive. Altering your final drive will make your car quicker than any power mod would, otherwise just stick a supercharger or turbo kit on it if you are dead set on chasing killer wasps and away you go =]
