The gas is pump 92 oct from Costco, surprised its struggling so much with only 17 psi. Dave, before the Pure turbos went on and I was still running the stock ones you were able to help me narrow down my timing issues were remedied by adding a few gallons of E85. This helped with the erratic timing across cylinders. However, if I remember correctly my avg ign was still around 4 in map 2 even with 3 gallons of E85. I feel like something else must be contributing to the timing problems. My next steps will to replacing plugs and running a compression test. E85 is hard to get, about an hour drive. I was hoping for better pump performance, don't most N54 run Map 2 on pump with decent timing?

Should I be resetting any adaptations now with the new turbos, or when I am switching up the fueling?
