Need Some HELP
I was wondering in a 3rd gen 7 whats the fuel presure supose to be with 750 primarys and 1600cc secadarys. at idle? The rx7 store did a awsome job on my car, but i think the fuel presure is to high at idle its right now 40psi. I'm running two walbro 255 in tank with -6 with a aftermarket fpr. Dam car is so rich, when i put the pedal to the floor you can smell and feel how rich its running. then when the turbo comes on it clears up the fuel pretty dam fast the car put down 450 rwhp and 339 torque at 20psi top end it strong bottom its just to rich. i know if i can get rid of some fuel presure it will be stronger bottom end as well as top end.
Rx7 store Jason and zavier highly recommend

Dropping the fuel pressure without changing the injector cycle will lean you out at the top and the bottom. Tune the rich lower RPM AFR with injector cycle and leave the top end alone
