Correct but just a couple of points.

*Will never throw a map 4 safety pull though. Only a "half engine" light.

*Only if it can't reach boost (will leave an underboost code). Or there is a timing pull. The JB4 works on octane based tuning as its the safest way to tune. So any anomalies in fuel could cause minor issues.

*Yup. If you can recreate the fault while logging you will nail it. Don't hold your breath.

Run some good logs and send to Terry for investigation. In the meantime get out there and waste some tyres.
