I have a problem with my 02 Sensors not getting ready with my stock 14 GT w/ GT500 mufflers. I found a remote tuner who seems legit and he says he can fix the problem. He insists I need to run his tune to do some logs, but then send him my ECU so he can "flash it directly".
Does this make any sense? I thought any flashing could be done with a file installed with a common tuner. Confused.
