But i mean my car was fine a few months ago, it wasnt missfiring at all, it was running smooth - as the car was completely stock at that time.
Now its running higher boost due to mods and if this requires you to gap the spark plugs to .8 instead of 1.1 then doesnt that mean the coilpack isnt giving enough power for the sparkplug to make the spark?
Because it always happends about 5000rpm thats probably peak boost and maximum power, I think when that happens the coils shit them selves or at least one cause they cant give enough power to the sparkplug.
Anyways keep us updated on what happens with ur car.
I will try taping up the coilpacks with electrical tape and gap the plugs to .8 and see if that does anything before buying splitfires.
