Sounds like a vacuum leak somewhere. What's your MAF grams/sec at idle, engine hot?

Dont have a current scan with the maf logging. My other scan shows a map reading of 48-53kpa with 29 degrees of timing. Way too much timing and the map seems a little low to me.

Sprayed the intake down with Carb clean and found vac leaks at the egr port, tb, and cylinders 6 + 8. Going to swap intakes and try everything again. I'll let y'all know how everything goes.
