Since I've put my exhaust on, randomly, I would get a check engine light due to my HFCs. However once every other month wasn't so bad. Last week it became a daily occurrence. My fuel economy didn't change, my AFR didn't change, and my performance hasn't changed, so time to do something about it. I called up Dynosty who did my tune, and they were great as always. They gave me all my options, I ended up picking up everything, including a bluetooth dongle, and they sent me a modified version of my map so my check engine light would stop coming on.
It will be nice not to be resetting that light every evening.
