TCU flash suggestions
For the last 3-4 years I've been using the Alpina flash on my car which for the most part has been great. There are two things I don't like about it and would like to change though. First off is the often complained about D mode with the lack of response and it being quick to get into 6th gear by 40. Secondly and more importantly, when my car is in S mode and I come to a stop, the downshift into 1st gear is abrupt and sort of rough at times since being flashed. I've searched but haven't found if anyone has had the same problem with that or not. I'd like to change to a different flash where the D mode is more like stock and where it would hopefully address the downshift issue. I haven't kept up with the forums in a while so I'm sure what the latest and greatest is. Familiar with XHP though and read a little about a new sport flash some time ago. Not looking to race the car or autocross, just have it a little sportier than stock. Any help is appreciated, thanks!

The latest update for xhp customization module allows you to use stock shift maps in whatever mode you select.
I don't utilize it but it sounds like a stage 3 flash and customization module would be ideal for you, just use stock shift maps for drive mode and you're good. Stage 3 gives you true manual mode, which is nice and id heavily suggest it over 1 or 2.

And at that point just use their map because it isn't worth screwing your trans up for the cost of a map.
