Help me with spark plug gap
I'm running a stock TT conversion at 6 psi on NGK coppers BCP7ES, so they are the correct heat range. What gap are you guys running? I'm running the gap specified in the manual : .040. I'm getting a lot of knock under boost and suspect that this may be due to my spark plug gap as some helpful people have pointed out in another thread.
Any help is appreciated.
