There is no FPR on an 02 and up, the fuel injection system is a returnless type, fuel pressure is regulated at the pump. About the only adjustable feature is the ignition timing (after an adjustable timing set-up is installed), I suppose with intake, exhaust, and timing, you could probably squeeze another 10-20 hp out of the mod motor. Back before 11/01, I used to rag on the baby cammers, but after buying one, I've found alot of respect for the 4.6 Its a good engine, especially when you look at the hp and tq #'s 260 hp and 300 ft/lbs of torque. Compared to the 5.0's peak of 225/300.
