All right so i recently installed some 660 injectors. i compensated them with the maft but i still have a really rough idle. mods are in profile. The idle surges and bounces around 740-900 rpms. when i get off the gas to coast the car seems like it wants to die. I have no boost leaks or vaccum leaks. Would raising my idle help. I have access to a scan tool so i can adjust the biss properly?
 
nope checked the tps, back probed it got good voltage. and i can see in my safc it reads fine. Im thinkin its my fuel pressure. i have an fpr on the way i think once i start messin around with that ill be able to fix it.
