But do you have random lean spots or is your fueling just maxed out with this st2 tune?
Fuelling must be around its max. It's 317cc injectors @ 4 bar. I could check injector DC. From what i can tell looking at VCDS it really appears to be random lean spots for whatever reason. WOT looks good, idle sometimes good other minute way to lean same for cruise/slow accelerating load. Slowly accelerating also comes with missfires but not every time.
