I have read where other A5's can squeal the tires into second gear and until tonight I thought, BS! Well I took a buddy for a ride after installing the Pypes exhaust a couple weeks ago, anyway there is an on ramp onto the highway close to the house that I like to open it up on and the 1 to 2 shift broke the tires loose! I realize this is kinda childish and no big deal but the car has not shifted we'll into second at all so I was shocked when it did it? With 1400 miles on the clock I'm wondering if the TCM is still learning? I know the first few times I got on it full throttle I let up on the pedal because I thought it was revving too high, and the last couple times I have left my foot in it? I have been researching valve bodies, TCM's etc to fix the lazy 1-2 shift, now it seems ok? The corrected altitude is well over 6,000 ft above sea level even this time of year, so I don't expect sea level power but it sure felt good tonight!
