Sounds like maybe a bit of valve float. IMHO

What type of ignition, and what rev limiter chip do you have in it ?

while I can't say what rpm they are good for I do know that I was told to use a crank trigger and not use the crank signal from my dual sync....
Rich Nedbal of Fastman Efi said it would not be as accurate as the crank trigger.....

Crane HI-6 with LX92 coil. That only has one rev limiter and that is set for the starting line launch. The EFI has a high side that I have set at 7500 that I raised to see if that had any impact.

Bobby,

When in sequential mode it is not triggered by RPM. It will be active at all times.

Hey cooter are you talking about the rev limiter?
