Ok after coming back from Germany car had been feeling a bit flat and developed a miss in 4th gear on boost, after taking the car to the rr day at APT it came clear that the car is over fueling just a tad

Need an idea of what things to check and how please? as Field Motorsport is really busy at the moment and not sure when they can look at my car

Also Jonno checked the resistance of the ECT sensor and want to know how accurate it needs to be? on cold it matched up but when coolant temp was at 80° it was about 100Ω out?
