So I recently bought a new fuel system and will be installing it this weekend. It consists of a Glenn's sumped tank, magnafuel 750 pump, -10an feed, -8an return, fore f2i regulator, mmr rails, 80s on e85.. I'm tuning with PRP and Iv never tuned for an adjustable fuel regulator. My plan is to set base fuel pressure to 42lbs add 30% fuel across the board from my 93 tune to make up for e85. With the FPR being boost 1:1 referenced what do I need to change in the tune when the car sees boost? If the regulator is adding pressure throughout the pull will I need to take fuel away from the upper rpm range? I'm taking my current 93 tune that was tuned on a stock regulator and will be adding these fuel components. If the regulator is adding fuel as boost rises and the tune is also then won't I need to pull away some from the tune?
thanks for any guys
