Adj. fuel pressure regulator

Post by 94mxthree »

Would running one help the performance of the motor?.Would running a higher pressure help at all?.Need some feedback thanks.

What if i got bigger fuel injectors with a different intake,would that justify adjusting the pressure?.

NO if ur boosted thats a different story..

and if u put bigger injectors what management would u use to control them

because putting larger injectors on the stock ECU might make ur ECU go out of control.

and what do u mean by different intake

intake manifold
cold air intake (CAI)

there's a lot more to performance than just slapping it on research and search for what ur trying to do. I did and well im happy with what i got..

Like this u can't have all three

Cheap
FAST
Reliable

U can be Cheap and Fast but not Reliable

you wouldnt need crazy big injectors for the intake mani, CAI exhaust.....

I would say a set of BP injectors would be fine and to control them i would use a Apex-i SAFC!!! But you wouldnt really need injctors or management to run the intake becaue the stock injectors are not maxed out and the ECU is setuo to be running a little rich for engine safety anyways, so the intake CAI would compensate and make for a better ratio!!!

do not mess with your fuel system unless you have some sort of forced induction. No, "ram air" does not count.
