So I have a 15 brz limited 6mt. I picked up an oft and flashed the appropriate stage one ROM for my calibration #. My car is basically stock aside from a k&n drop in. I have waited 5 days before posting here. I cannot tell any difference from the stock tune. I wanted to ask you guys if there's a considerable difference with a stock car.

Thanks in advance...
