should i change fuel pressure regulator
So i have bored out the throttle body, did an evoms air intake, enlarged the intake pipe, and installed an ipd plenum
Engine is definatly breathing more air, i can actually hear it sucking in air.
Now i have found some sites suggesting that to take full advantage of the extra air that is being sucked in, its best to change the fuel pressure regulator to one with 4 bar. as far as i know, the standard is 3.8 bar.
My mechanic told me that he doesnt think it will make much difference since the ecu is already telling the injectors how much fuel they need to inject, according to the amount of air that is being sucked in.
any ideas please?
