So say you wanted to run 21psi on a 2.5bar MAP sensor, it would constantly hit boost cut at 22.8psi despite being on target boost or target 18psi and get 20psi boost cut constantly too.

Ideally, you want a boost cut set at a safe level. If the boost target was 17psi, the boost cut was 22psi and the CEL was disabled, then I would have an issue with that.


For example, guy I just met in Perth had boost cut set at 26psi today on his 3 port tune. Target boost was 16psi and waste gate pressure was 17.6psi

So the answer to the OP's question is... Tuner should avoid having boost cut table left stock when boost is raised
