I am in FULL agreement that there is a fuel flow issue.
But is it one or all of the following:
Electrical
- The demand signal
- The demand signal feedback loop
- A sensor somewhere giving false information
Mechanical
- The fuel pump not responding to the demand flow (main jet / pilot jet issue??? lol )
- A filter
- Mechanical feedback in the throttle body

I believe it's in the ECU - no one with a Guhl reflash has had this problem.
Can't wait to get mine to him and back.

I also want to see if GaTeach's mech had the solution.
