Well, my mechanic said my car is most likely chipped, how could I find that out? Do you guys have a pick of the original so that I can look to see if it's still in there? Or do chippers usually just change the programing not the chip itself? Thanks!
99.9% of the time chipped cars don't throw codes unless there is a problem with the car itself. easiest check is to log boost...however your '99 does not have this sensor, so log MAF instead.....if it peaks out at 150-165+ g/sec then its probably chipped.
