mate i wud strongly advice a set up regardless of runnin in... not a rolling road set up...

just cam timing, ignition timing and CO levels... i bet that has alot to do with ur problem...

ud b shocked on the difference of a MFi car depending on its set up!


im sure any garage with a CO machine cud do it for bout £30... worth every penny...

also as sed check servo is ok and check for any air leaks as the car runs of vacuum.
