Hi all. I have installed a Harrop 2650 (also upgraded fuel pump and full exhaust) and have a bit of an odd issue. Under WOT for a couple of gear changes the engine derates and then is slow to accelerate etc, shut engine down and start again and it?s fine. I wanted to have a look at the thermocouple tables to see if there was some sort of temperature cat protection but don?t see anywhere if these tables exist (the factory thermocouples are retained). Has anyone come across this issue? FYI there is no knock in the scanner or faults in ECU when problem occurs.
