peak was ~ 6 before tune up . I did not check the base before tune up . tune up was using a tank of gas treated with larger bottle of techron ( treats up to 20 gallons gas ) , ngk bcpr7eix plugs , bosch cap & rotor , bougicord wires , mann air filter and an amm adjustment which obtained a swinging 0 - 12 volt reading at the test socket near the power steering resavior . I checked the base boost by diconnecting the electrical plug at the apc solenoid . what is the likely culprit(s) for the 2 base and 9 peak after the tune up ? the car idles and runs well otherwise . thanks in advance . ps - car has ~ 220k on it and I have not touched the wastegate actuator or the apc box yet .
