When i chip my P13 with a Skunk2 chip (VTEC-5500,RL-9000) i was told that it would be necessary to get a fuel pressure regulator to turn up my pressure sinse the chip will lean me out at high RPMs , sounds scary. Will it really be necessary or will my ecu compensate enough not to let the engine starve itself of fuel. Thanks guys.

Only a wideband will get you that answer. I guess to be safe, upping the fuel pressure is a good idea but then if you up it too much, you'll run rich and negate the power gains you just got by chipping your ecu.

AFAIK, chipped ECUs don't do any more fuel compensations.. they've been chipped for one particular ignition/fuel map and that's it.
