V9 but misfire

2500-6500

hey steven so here i have correct options selected via mhd and pulls went fine i’ve also added f8s ngk e85 bmw plugs and i’ve also added the b58 coil conversion kit and selected that option as well

Tried a 4th gear pull but it smoked the tyres once boost came on. Then tried a 5th gear pull; no tyre spinning but it started to break up a bit with misfires. Was still pulling strong. New Bosch coils and new one step colder NGK with stock gap (0.030”?). I’ll swap out to new Eldor coils tomorrow and new 2 step colder plugs with 0.024” gap.
