ACTs on a light cruise are TOTALLY AND UTTERLY IRRELEVANT . Go see what it is on full chat .

However, if it exceeds 60+°C (back off straight away), you need to think about WI and/or a better intercooler .

Who-ever live mapped the car would have done so connected to the ECU, so would have mapped it to the boost pressures the car was seeing NOT a shonky aftermarket boost gauge .
