Hi again. I have a ‘23 GT2 and installed the HKS plugs and Typhoon air intakes along with the JB4. I was able to go out today as nice day in winter. Set it to MAP 2 since I run 93, and went down the road. Looking at the phone screen it showed zero boost even at WOT. Turned it back to MAP 0 and same thing—zero boost. Ideas?
