Right, I seem to be boosting more than it should be. The spec of the car is: NGK HT leads Blitz nur spec exhaust Relocated air filter Tein springs Autogauge boost gauge It seems to just keep creeping on full boost from 0.6 to like 0.85 at which point my engine light comes on. I checked this in 4th as I still have standard mani on. What could cause this and what are the solutions?
