View Full Version : High Boost Misfiring...

Has anyone here experienced a problem with your motor cutting out at high boost? (15+psi) If so, how did you remedy it? Do I need better plugs? Tighter gap? Im running NGK BKR7'S...

Couple things I did:

1) HKS TwinPower Ignition control unit
2) 0.030" gap or less on sparkplug.

Previously, 0.035" gapped plugs worked for me, until the colder winter weather arrived.

On a KA+T.
