Fuel pressure?

LX XLR8R · 05-22-2001, 12:15 PM

jimberg..what is ur basis for that information??what u r basically saying is that no matter what pressure i set my car at the computer will learn this and go back to the stock settings???well i can say that is wrong at least on my cars and ones that ive worked on...my car with heads, intake, cams, exhaust 24#ers and 77mm mass air will not run at the stock FP no matter how many weeks i drive around at 38psi..my car will cut out up top and my plugs will be glazed...i have 24# injectors but i still need to bump up the FP to keep up with the incomming air..my car will run good at 42-45 psi depending on weather..now people running EGT gauges(serios tuners IE tropphy stock) and running 1340deg constant run after run..day after day, do they reset thier computer every day???and why make adj regualtors at all if the computer will reset it anyways??

i do agree that 70mm TB is too big also..i run one cuz A) i have at least 3.73's if not 4.10's in my rear at all times, and B) my cam although big makes increadible tourque and needs to breathe wll up top

does the pop come when ur getting on it or when you are decelerating??
