This has not been a big issue, but it was today on the track.
It seems that I have some kind of grimlin in my coil or ignition system. Under load and hard driving the motor will just put out enough power to barley maintain rpm and also some times cut out in the upper rpm range. The Tac will also "flutter" when boost kicks in, that is it will drop down and then bump up.
I was going to start checking grounds from the coil back. Any suggestions or experience with this issue? Thanks
