I'm having a couple issues.

For the most part the Fitech has been excellent.yesterday I towed my 12k lb boat and climbing a tall bridge the engine went into a pinging fit.I pulled over and saw the fuel pressure was at 50psi at idle and would go to 59 when you revved the engine in park I changed the fuel filter with no change.when I remove the vacuum line at the fuel pressure regulator the fuel pressure jumps up to 59 psi at idle.
Also I had to reset the TPS learn because it was reading 0 at idle.

Try some higher octane.

Thanks for the response Austin.
Is the fuel pressure normal? When I installed this unit it was idling with 58lbs

Keep an eye on it. Not something I am concerned with at this point.
