i just installed a amp fuel pressure regulator on my 07 m8. I have slp pie and can and v force reeds also been clutched so my quesion is what should i run for fuel pressure i fired it up with the stock regulator it was 45 psi
i'm running about the same setup w/o the reeds. Really thinking about a regulator. I'm curious what gains you see from it. I believe SLP test's their pipes at 48 psi, I'm sure someone smarter than me will pipe up and let you know for sure.
I emailed slp and asked what i should run for pressure with slp single, ypipe, can with rtk head and bdx intake and all they replied back was 45 psi was stock and should use controller. I had my gauge checked at the cal lab at work and it was about 1lb low at 45 so when i checked my sled with the stock reg it as 44 + 1 = 45lb. Going to start at 48 and see how plugs look.
thanks for the info guys i think im gonna do the same start at 48 and go from there the only prob with my regulator is i have to adjust at the bottom of the fuel pump lol
