fuel vs air
hello
i want to know if the fuel pressure at ten psi of boost at some throttle will be the same at full throttle. the reason being that when i reach ten psi at not all throttle the car feels muchs stronger than at wide open throttle. basically when i adjust the Begi Afpr and at ten psi the ~105psi fuel should be at wide open throttle or not?
thanks

adjust the fmu see peak fuel pressure gain at full boost & wot.
probably runs you a little leaner when not wot so you'll feel more power, i'll take a wideband log of the same and see what it does, never tried it before.

so i checked the fuel pressure. and at wide open throttle at 10 psi, the pressure gauge reads 120psi of fuel. i guess this is too mucch. so i loosen up the afpr bolt more and the change is so minimal. i guess the only thing left is to put the little restrictor included on the negi afpr kit. am i right or not?
thanks
thanks
