hey guys i am the pround owner of a 92 gtst type m, currently my car is basicly stock (enginewise) with a few minor mods such as
- 3inch straight through exhaust with twin 3inch muffler
- gizzmo MS-IBC
- bmc high flow panel filter
it has a bad missfiring problem! i have changed the plugs check the coils all in working order, changed the feul filter basically service the whole engine bay but cant get ridd of this missfiring problem, it generaly happens under hard boost from 5000 rpm till redline, ive basically brang it down to a computer problem. on the cards however is a nistune remap and dyno.... but before i did that i have planed on installing a vg30, plus frount mout, and proper CAI System on the car.......
what are your opinions Remap first then mods or live with it for a couple of months until mods are done and the remap?
and any advice or input on the missfiring would be appreciated?
cheers Joe
