So basically we recently got the car tuned and we had an issue with the car not holding boost. The car would rev up and only boost up to 2 psi. We have the carbon canister hooked up to the car and only when we unplug the MAF and clog the vacuum line (EVAP line) that goes to the carbon canister does it make its normal amount of boost. We've tried unplugging the MAF and keeping the carbon canister plugged in, we've tried clogging the carbon canister and keeping the MAF plugged in and we've tried plugging the MAF in and the vacuum line into the carbon canister but we still only get 2 psi. The only way we can hold boost is if we clog the vacuum line and unplug the MAF. Any ideas?
