I have a 2018 GTI SE DSG and have both the APR Stage 1 ECU and TCU tunes. I like the TCU tune for the most part (power wise) but there are also some things I don't like. Of course we all know there are the drive choices on the touch screen (ECO, NORMAL, SPORT) and also two separate automatic drive "modes" (Reg Drive and Sport Drive). I have found that the Reg Drive is pretty much worthless with the TCU tune in my opinion and this was also the opinion of the technician who installed the APR tunes and test drove the car after installation! In Reg Drive mode the thing will shift into 6th at like 40MPH, 5th at 30-35, 4th at 25-30! This didn't really bother me that much as I was never going to be out of Sport Drive at all unless I forget to put that in place before I go (and I always keep in in the SPORT choice on the touchscreen). BUT, the Sport Drive shifts also give me some issues as I have found that during daily driving conditions it will shift from 3rd to 4th at 38 MPH and 4th to 5th at around 54/55 MPH. Also sometimes at these speeds the tranny seems to not know what gear it wants to be in and goes back and forth causing a "jerky" motion/feeling. It also does this sometimes between 2nd and 3rd. Of course all of that goes away if you use the Manual Drive and shift yourself from either the paddles of the gear lever. Anyone else have these issues? I wish you could program it that in SPORT Drive it would go into 4th around 42-44 MPH and into 5th at around 58-60 MPH!
