Just wanted to say a big thanks to you folks on here for helping me to get my A6 to shift like it should! I used the stepped oncoming pressure presets values posted by Tre-Cool on here and now my car shifts instantly at WOT. After I added a Heartbeat blower, I had a serious problem with getting my GS to shift at WOT, as it would just over rev and bang against the limiter. Even after 4 retunes via remote Autocal service by a big name tuner, it was still doing it, and I had to jack the shift speeds down by several mph just to get it to initiate the shift early enough to complete the shift before hitting the limiter.
I purchased the Tuning School manual and followed their recommendations and it was working good after that, but I still felt like the shifts were taking too long.
Now, with Tre-Cools settings, after a reset/preset (thanks 5FDP!!) it shifts like the Coan TH-400 in my race car - instantly- at WOT, and nice and firm, but not violent, at cruise. The only thing is that it shifts so quick now that I need to tweak the shift speeds slightly upwards again.
So, a big thank you to you guys!!
