ok,so ive always heard LO3 run on the lean side from the factory,well ive also removed the AIR system.

so that mean my car is gonna be runing more lean now?

what is stock fuel pressure,PSI?

how much should i raise it?

whats a good not to pricey regulator?i saw somewhere bout putting a washer in the stock one would raise it,this safe or true?

will this make it a good bit peppier?

bump

These cars run rather rich from the factory. You can add some SA.

Put the air sistem back on, the only thing that happens by removing it, is your cat no longer reduces the toxic gasses as it is supposed to.

11.5-12.5 psi

Use the search option and read the stikies to find out how to make it peppier.

What you probably heard is that lo3 fuel pumps are garbage, which is true.

well that wouldnt surpise me,pretty much eevrything factory on these cars are garbage.

Just so nobody gets the wrong idea here, LO3 fuel pumps are "garbage" when it comes to trying to use them to feed engines of significantly higher-than-stock performance.

For stock or near stock setups, they are fantastic. Quiet and damn near bulletproof.

My stock pump just took a bullet, putting in another today, Got the TPI version so if more mods come along dont gotta replace the fuel pump, just the Pressure Regulator


I wouldn't say everything on these cars are crap Just some bad designs but thats with every car.
