So I had my TSI (manual trans) flashed by APR at Waterfest this year. I'm loving the added power and everything that goes with it..... but I developed a weird side effect. I doubt it's anything to be overly concerned about, but when I start my car (in neutral of course, with the clutch depressed) the pedal itself does a brief vibration, similar to what you would feel on the brake pedal when traction control/ABS interferes. After this it doesn't happen until next time the car is started. Has anyone else experienced anything similar? Can anyone offer any insight as to what it could be? Thanks !
