    Lee, firstly welcome to the club. Anymore details on this issue???... Does it sound like an Engine Knock a wheel whining, gearbox crunching etc?.. The more specific or detailed you can be, the easier you may get some answers..

    Could be detonation or pre-ignition. Is it a decent map, i.e, from a reputable source?

    Lee, I believe Monty is stating that the map could be what is at fault for the current issues you are having. My advice would be to either put a standard map if you have one back on your car, or at least revert back to the phase 1 map you had on your car and see if the problem you described persists.

    If your current stage 2 map is causing detonation, this is obviously not a good thing and a quick way to say goodbye to your engine, when a piston decides he is fed up of working and hands in his notice.
