This is on a gen3 coyote and only has a few bolt ons and a tune.
The car goes 20% lean at idle and also runs lean while driving, we noticed this after switching from flex to 93. The tank was drained before switching and we have smoke tested the car 3 times at different shops and no one could find a vacuum leak.
I noticed that there is only 1 PID for LTFTs, it seems to be missing bank 2, could that be part of the issue? Should we try swapping the sensors around or is this just a bad tune?
The tuner is no help, keeps giving revisions with the same problem. I suggested that my friend switch to a reputable tuner but he is trying to get this to work since he already paid the guy.
