I have a 2018 F150 here at the shop we just installed an eforce supercharger kit with the tune provided from edelbrock . We Strapped it on the Dyno and tried to make some pulls the truck makes about 8 psi then at about 4000rpm loses all boost . So we datalogged it and it looks like the throttle body is closing both the commanded throttle body angle and actual are reading the same so something must be telling this thing to close . looking for ideas here both myself and edelbrock are lost . There are no engine lights on
