what about the air intake temp sensor?
maf can be somewhat disabled in the tune but not permanently deleted; in order to revert to sd mode.

that 200 code needs to be fixed.
maf code is from the sd tune, which is ok; and the maf not being present.
if the alternator is charging, delete the code.

I know im not getting enough Voltage to the injectors- drops to 8.5v. I have 2 separate banks one for drivers and one for passenger. I used 14 gauge to feed, Is that too much too little? Any other ideas? Thanks man
