      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

      I was going to ask if it only happened under load or did it also happen wh en free revving, But i see you had already mentioned this.

      I would keep a mind towards what the motor is doing, under load, during high torque outputs. As in shifting in the mounts, straining both Air Intake 'stuff' and Electrical Connections.

      Another thought is that normal driving can better deal with a marginal voltage, augmenting your supply and esp Grounding might provide more 'sump' of good, clean 12-14v.

      And of course, Seafoam isn't a bad idea.

      That Marginal Voltage is exactly what I think the problem is.
      The car has had electrical issues in the past where the head lights would go out when the high beams would turn on. Had a burnt up connection behind the fuse panel. Similar problem here I hope. Just got to trace some wires.
