Decreased engine performance is defined as a Fuel Pressure Regulator 1 Exceeded Control Limits - Pressure Too Low I currently running a stick Whipple tune, I use she’ll gas religiously but had a recent fill up on Sunoco 93 and on a WOT pull got this CEL, have not had this problem before Also what is normal fuel pressure range?

Sounds like your running out of fuel to me. Your fuel pressure at wot should be around 2100 to 2200.

get a datalog of a wot pull and we can tell you exactly what's wrong. the last time i had that same CEL; i had 40% ethanol mixed in the tank and the car ran out of high pressure fuel.
the datalog will tell you exactly where the problem is best of luck; before putting the car into limp mode again; find out what exactly the problem is and address it

If you use the tune from Whipple, check the desired fuel pressure. It usually makes the trouble. I had the same issue.
