On hptuners scanner, IAC is show values as the car warms up, but drops to 0 when the car starts driving and comes to a stop
I did a smoke test and find only the IAC itself leaking, did a temp fix but it still does the same thing.

With regards to the IAC, once an engine is warmed up it shouldn't be running or be used anymore. If it is then there's potentially a problem with the engine. Now to the KR your getting, i can't really see any reason for the KR unless the car is really lean in that spot. the computer is commanding an AFR of 11.5:1 or roughly 0.77 lambda which is where i would typically like to see a boosted engine on gasoline. If you have a wideband with a data output wire, id get that wired into your MPVI device so you can datalog that and see if there is any sort of hole in your fueling tables.Originally Posted by LuminousX
I just put in some 36lb injectors, can I bump my fuel pressure up to get the most out of them, how do I go about that?
