Delicious tune, so MAF I guess. Stock everything except SC.
No, the fuel trims maxing out is new, normally it is about -9%. Definitely don't have an air leak anywhere. I'm running a Shorai battery now that it is warm, just to rule that out I put my big AGM winter battery back in and ran an 8 gauge wire right from negative terminal to the ECU.
I was wrong to get excited about the reset fixing it, stalled a couple times again this morning. Definitely only does it when cold, once the dash gauge gets to the middle the car runs great and fuel trims go back to normal.
I do have a Dbox and I've heard of those failing. I think I'm going to email Delicious and ask if I can have a normal v25 map without the Dbox adjustments and disconnect it just to rule that out.
