i got msd, aem fuel rail, regulator, some off brand injectors, vafc2, high compression build.

Problem is when under lug, or at high RPM seems like its loseing power, like its not really lugging out but feels more like a bad spark plug wire, kinda like cutting out on power here and there.... its annoying. An its way worse when i have my ac on... sowa yeah out here tyrin to trubble shoot. would like to fix my self its kinda a hobby. When it lugs down like 2k on 5th gear mobin through town i sair i can here like backfire/poping sound. But idono.....

Maybe my msd coil is bad/ not good enough ground?
bunk injectors?

my car is a 95 gsr with 1st gen b16a ecu. i think a p30 is it? chipped.. i have my stock gsr ecu as well.

 

wow.... take your car to a tuner to have it PROPERLY TUNED before you destroy it.
