Chris Wilson Posted April 21, 2012 Share Posted April 21, 2012 You need to measure the injector duty at full boost, and the fuel pressure at the injector rail. It is possible to fit a UK MAF sensor the wrong way round, it has an arrow on it that SHOULD point to the engine. It won't idle too well when in the wrong way around, but it will run. It will run lean at high air flow demand situations.... Worth checking. Otherwise it's just normal EFI diagnostics. Quote Link to comment Share on other sites More sharing options...
