heres the deal trying to beef up my 93 chevy a little. alot of web sites i go to say replacing the fuel pressure regulator with an adjustable one helps out. the thing is do i need to buy a $65-75 bolt on regulator that goes on the tb housing or can i just get an inline one that are easy to find on ebay!!! my only concern is that the stock one is supose to be between 9-13psi. if i get an inline one (mounted before the factory mounted one) will it mess up the factory one or will the factory one regulate it back down to the 9-13. could i just block off the factory holes with a block off plate? i already know the computer dont control the psi of the injectors so i dont have to worry about that. please help i want more power but dont want r@pped while doing it.
