i recently put an msd setup in my car and now my car is busting up at about 7000-7500rpm and i dont know why. i have a b20vtec with s2im,vafc,ctr cams and s2 gears,rc 310s, dc header [not jdm]. i am also running denso iridiums with a .055 gap. i have tried to add more fuel in the upper rpm range and it was still doing it. any ideas?
