Speedinc tune issues with my A6 trans - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I had Speedinc tune my car over a year ago and ever since it seems to have problems downshifting. For example when I drive 30-40mph and punch it, it downshifts and launches hard for less then a second then it seems to pop out of gear and downshifts again right away. All this happens within 1 second. It is really annoying and embarrassing when I try to get on it a bit especially when passing another car. I do not have any problems using tap shift to manually shift. I have been driving the car in manual mode to avoid this issue. Sort of defeats the purpose of an Auto.

I took the car back and Speed inc attached the computer to my car's computer while I was driving and logged the data. They saw the problem and admitted that it shouldn't be this way but couldn't explain why it was doing it so they put the stock file back in the car to see if the problem would go away. Once the car was back to the stock tune, I had no issues whatsoever. Once this was verified they programmed the modified file back into the car but this time they disabled torque management and the problem went away for few weeks but surfaced back.

Has anyone experienced similar issues with their Auto after a tune? I don't feel confident in having them alter the parameters any further and am thinking to go back and have them tune my car back to stock then take the car to another shop for a brand new tune. Any suggestions are appreciated.

thanks

I would say there may be a problem with commanded shift timing.

I have the same problem with mine without even tuning it, and I took it to the dealer and they told me that there is nothing wrong with it. I have noticed that it does that only on the first luanch when the car is cold but after driving it for a while shifting becomes normal. I'm still trying to figure out whats wrong and it could be a programming issue from the shift timing comand as mentioned.

You will eventually find out that the a6 was made to give mpg and not performance. After about 600rwhp they give up even with the best tune you can get.
