LML fueling

[ikeG]

Have a 15 LML in here. Tuned, SOTF switch, non compliant. It runs super lazy and sluggish, checked all the normal stuff. I noticed it maxes out at a desired FRP of 72xx psi. Ive tried all positions of the SOTF switch, cleaned MAF, checked air filter, etc. What would limit the desired rail pressure, except for the tune itself? Ive not ran into this one before.

MAF, MAT, ECT, etc all the usual suspects. How's the boost? If you demand full fuel pressure with your scanner, will it max out the actual fuel pressure?

Fuel temperature would be my first thought. Isn't that how they do it on the LML switchable tuning? Maybe somethings up with the SOTF switch. What does the scanner say for fuel temperature?

I'll dig into that stuff tomorrow. Thanks guys
