mate at work has been messing with the mapping on his bugeye suburu. downloaded free software from the net onto a laptop and got an obd cable for 6 quid. he has had a group 'n' rally map installed for a few days( lots of popping and backfiring). currently has launch control running and has been changing all sorts of parameters, and currently running (estimated) in excess of 300bhp. anyone on here tried doing it themselves?
if i didnt have a new insignia and was running something out of warrenty, i'd be interested in trying it myself.
