Seems to be a multitude of things, but after pulling the ROM looking at the tables here, this was tuned right to the ragged edge, really didn't have any buffer room for error. The car has a defi link system and I did a recall of peak boost and it also seems like the owner turned up the MBC a little more than he should have or what the car was actually tuned for. And it's also apparent that this guy beats this thing like a dead horse. So can't really truly point the finger at the tuning. Had it been driven normally and not futzed with further im pretty sure the tune would have be OKAY for this, still doesn't look great, but just mediocre in my opinion.
