The Borla was certainly too loud for me, I am enjoying the open flapper on stock exhaust, to be honest I even consider asking Jeff to set the flapper back to stock, but sometimes I like it open all the time so I am going to leave it alone for now.
As for the UM combo tune, do it, if I knew how great a mod it is, it would have been the absolute first thing I did. Honestly, VW needs to hire Jeff and have him tune all their cars. Either way, it is a must do mod, you will not regret it. DO NOT expect noticeable power, but do expect a smarter car that you feel more connected to.
While I am on the subject I want to add a few more items to my review of the UM combo tune. I have found that S mode is much much more pleasant than without the tune. The downshifts are 10 fold smoother and you can even use S mode around town without looking like your driving a manual for the first time from the outside
All my initial comments have held up for the long term driving. I have done a lot of city as well as freeway long distance. On the freeway the car feels stronger, passes better, that is really when you will notice the power gains shine.
As for the R to D confusion, it is better, but still not perfect, from time to time, even with UM it gets confused, not nearly as much as before and the confusion is not as noticeable when it does happen. I really hope Jeff can 100% kill this symptom, sometimes you pull out in R and for safety reasons need to get into D and take off quickly, so the solution of shift, wait, wait, wait, then go is not acceptable to me.
One more thing that would absolutely make me thrilled is if UM could somehow find a way to switch the shifting pattern to what BMW has done, the stick feels reversed to me, I want to move the stick forward when decelerating to down shift, then move the stick backwards when accelerating to upshift. Basically the motion of the stick should be in the same direction as my body is being pushed. Just a preference, I will likely have a conversation with Jeff about this to see if he thinks it possible or not.
