I'm sure that would drop a bit in Map 4 with meth. My boost target is also 2 psi lower without meth. I included fuel pressure because I'm running the new booster pump if anyone was interested. Prior to putting the booster pump, I was getting low pressure codes running 60% or higher Ethanol content.
At the time of this run, Ethanol % was at 81.2% according to my Flex Fuel sensor.
what would this vehicle dyno and why such low boost?
