I wrote a while back about how my car was sputtering really bad and wouldn't rev over 5500rpm. I now have 2.5inch exhaust all the way back with a magnaflow muffler and no cat. After the exhaust was put on i would rev to bout 6200-6300 rpm. Today I changed the sparkplugs from platinum 4's to NGK Vpower's and it will now rev to 7k, but it still sputters and will not rev any higher.
so does anyone have any idea why it is still sputtering?
My setup:
b16a
total seal piston rings
new oem headgasket
exedy clutch
msd blaster ss coil and cap
NGK vpower
ssautochrome mani
t3/to4e 8psi

dsm 450's
