as topic says after i put my headers on if the trans drops down 2 gears or when the motor wines up at about 4grand rpm it starts sputtering. please help me! along with the headers i put on some msd wires. my mod list is as follws: intake, zzp pcm, down pipe without cat, shift kit, autolight 104's, 42.5 injectors. as far as the pcm goes it has the normal 1.0 file plus rear o2 and bigger injectors added to it.. this is my only car so i need to fix asap!!!!
