Is it true that AAN doesnt have owerboost option? I have instaled AAN engine to S2 and I have MTM remaped AAN motronic. IS it beter to get aby one or should this be ok? The car is not on the road so I cannot test the performance.

If the ECU's been tweaked it might be running overboost boost pressure all of the time (i.e. not just under high load in high gears) and that's why you suspect there's no overboost. I'm no mapping expert mind.David

I seriously doubt that MTM vould take this ceap trick. An i newer tested it due to the car is in the garage. It was basicly a metter of someone claiming that there is no owerboost feature.

Means that AAN has also 380Nm torque, same as ABY?S2 limoComment

Doesn't the MRC high boost chip go up to 1.5bar and isn't this above stock overboost pressure? I wouldn't know as I have a 3B. Although my point is pointless
if the claim was that AANs in general have no overboost rather than your MTM AAN doesn't have overboost.

I think that chipped cars, will have maximum boost all the time, not only for a few second like AAN, but i guees i might be wrongComment

Electronicaly AAN and ABY ECU's are the same. Their might be a starter-lock on some ECUs, so make sure that is removed.Comment
