do any of you guys sometimes reload your tune and find that it will run like the tune is supposed to make it run, then 50 +/- miles later you don't feel the same power as you did?
I had something like that happen also. This one was obvious. I had the car dyno tuned and the 91 octane tune install. At the same time the traction control was disabled. 2 start-ups later the traction control was back on and it felt down on power. How could the traction control go from off all the time, back to factory with the default on?
