I have a 2016 WRX and just got protuned on e85. When I let off the gas after some decent throttle, my fuel pressure drops down pretty low, as low as 30PSI then it goes back up. Sometimes happens when first pressing on throttle. I just installed a DW 65C and it didn't fix the issue, made it slightly better but didn't fix it. Please shine some light on this issue, thank you!
