I got my tune with 800 miles on the car and have not noticed any slippage of the clutch. Right near the post 100 mile break-in mark, i did a full launch control start and while i spun through 3rd and noticed the transmission really did not want to shift while the tires are in free spin ( who would have guessed), I have not had any issues with slippage.
And Patrick, the ticket was on I35 in Kyle. I commute to work every day in San Marcos (30 miles each way). Ive been doing this for years and always cruise at 80 with zero police interactions. I have an escort 8500 but I was hit by laser and you cant really do much when that happens.
