Ok.........................
2..1 z24 2.4L twin cam 5 speed supercharged with the m45 gm kit. stock 2.8" pulley. coil swap conversion with msd coils. TR6 plugs gapped at .028. i had them at .030 , .035 and so on but no real difference. Coolingmist meth injection with whatever nozzle that comes with it. The car is getting a misfire at high rpms (like really close to redline and it seems to only be in 4th gear) I keep throwing a p0300 code, random/multiple cylinder misfires. now it does it with or without the meth hooked up so im really in the dark with this one here guys. What the hell is going on with my car???? its also got the rsm aluminum crank pulley and motor mounts. i ran a 14.8 @ 92mph last sunday at the local track and it was throwing codes around 5k rpm in 3rd on that day also. I pulled my plugs to check them and they are like a light tan/ sand color. No black soot or anything.

sorry guys i didnt realize my buddy was still signed in. can someone delete this post???
