You haven't listed the mods but fuel pressure is a universal mod failure problem.

Well that explains that then.

What's the pressure at idle and low load?

Fuel pressure.

It controls the AFR.

The computer has no idea what it is because there's no sensor.

That's pretty good for 2150's and gasoline, even e85 it's not bad. I had to reduce my timing some too get leaner AFR's at idle.

Are you running V7 tephra mods? If so knock down your timing idle correction to around 4~5 degrees this will help prevent hunting. Lower the base timing a few degrees in the idle load areas. If it idles to low you can increase your IAC counts in the look up table. Don't expect a steady 14.7 with those 2150's cause it ain't gonna happen.

If your really that worried about it you need to add this table to your rom and tune it to the 2150's. It's a PITA but once you get it dialed in it's sweet.
