Been running the Vector on my '17 S for a month. Tried 2 settings so far: Sport 4 (default setting) and Sport 6. Note that I'm calling 1 as lowest in mode and 7 as highest (7 settings per mode). Sport 6 is what the Flat6 said was their best setting in testing -- though they call it Sport 2 (With 1 being highest I guess?) The lights to indicate setting are a bit wonky as there are only 4 LEDs for 7 settings. and the lights don't exactly light in order. Kind of confusing...
Note: I drive in Sport mode, 93 gas, no other mods, and always warm-up the car until idle settles (except for one test--see warning below).
With the Vector in both settings, the Macan S performed more like I expected it to vs stock. Low-end shifting (up and down) felt noticeably smoother and more enjoyable around town. Sound on warm-up idle is a bit muted with the Vector for some reason, but haven't noticed any sound difference when driving. The problem: The shifts between 2-3 and 3-4 are clunky when punching it. It definitely has more acceleration, feels about 50HP to me? But the shift drops are significant and I can hear the wastegate (?). I've recently put in the plug to bring it back to stock and it is def not as fast, low-end slow shifting is not as smooth, but shifting is smoother at higher revs.
The jury is still out for me. I need to test other settings because the clunky shifting is a no-go for me. If I can't find a good balance, I'll sell it.
One warning: Make sure to let the car warm-up. Shifting and wastegate noise seems far more pronounced when cold. I tried this once to test and won't be repeating!
Installation was a bit cumbersome. Took me about 40 min, but most of that time was spent trying to get the plugs free from the stock sensors -- the Cam sensor was a pain -- and prob 15 min finding good places to ziptie the cables to avoid heat and allow the engine cover to reseat properly (LOTS OF CABLING!). I think I used 10 zipties, and they supplied 8 in the kit?
My biggest concern is cutting all those zipties and reinstalling if the car ever needs a service visit. Not looking forward to that! If you can find a suitable tie that is removable, please let me know!
