mine has been running for more than 3 months with what i presume is the standard ecu and no mapping......

Has been going well past 3k as well.. seems as though max boost is around 6300 without mapping :)

???
 
think if its way out , as in too far for the car to self adjust, youll get a code. i changed the maf to the 3 inch one and it still didnt throw a code until i fitted the fmic. then the cooler charge required more fuel than the car could cope with, so threw a code. quickly fixed by tt injectors. i drove mine like an idiot for 2 years with no remap. when i put her on the rollers, the fuelling wasnt that far out believe it or not, according to the guy doing the mapping.
 
mine seems to run completely fine and had no errors or any problems even after fitting the FMIC.

Will need to get booked into Jabba as soon as I save the money then!!!
