NGK says as a rule of thumb you should drop one heat range for each 100 horsepower over stock you are. This is pretty much BS, it seam to me that viii's run well with one step colder and ix like the factory heat range.
Also i have experienced these ignition miss fires and a common culprit is the plugs wires. i was down to .018 on the gap and it cleared it up, but when it was rainy or moist it would still do it so I knew something was up. Replaced my plug wires and ran 37psi on a .022 gap no issues.

My car is breaking up the same way. wouldnt let me get past 4k. Sounds like a 2 step everytime i try to push it. Started happening when i started running the meth. Should i get a different or stronger spark plug since im running meth ?

it never act up before but It started after I was running it constant. I changed the plugs to denso's. Are those better than the Ngk ? I also got a cam position sensor code that popped up. The afr is running fine on idol. Runs rich on WOT
