Thanks, that was helpful.

I think I would be running the stage one chip at the mo, as mine too is running pretty rich. Only just squeezed it thru the emissions tests here in italy.

Exactly what function does the 3 bar map sensor perform ? Is it some kind of enhanced fuelling sensor ?

With the upgrade of injector and chip, is it merely a swap over thing, and then check the fuelling, or do I need to get the car ro ro'd
