I broke down and bought a wideband to get my MAF dialed in. The fueling is dead on when I'm cruising around. That is until I turn on the AC. When I'm actually moving, it's only slightly lean, but when I come to a stop it goes WAY lean. When I first start it up with the A/C off, the idle is extremely smooth. Then switch the A/C on, and the idle is all over the place, and it runs lean.
I've tried messing with the Torque Model -> Loss -> A/C Compressor section, but it seems nothing changes when I make adjustments in there.
Any suggestions on where to look? I attached my current tune file, but like I said I have tested adjust the Torque Model-> Loss section in both directions to try and fix it and not luck.
