Thoughts on Cobb or GIAC?
#2
I've got a Cobb on my 2016 Turbo. I'm very happy with it. The Cobb really helps reduce the turbo lag, and combined with lowering springs, makes the car handle far better than it did before. It's faster & smoother than it was. I prefer the Cobb because I can uninstall the tune if I'm having the car serviced or need a PCM update, etc , & then reinstall it. The GIAC would need to be reloaded (at added expense) if there's a software update that overrides the tune. For me, the Cobb is just easier to work with. Plus, their customer service is great. I had an issue with the AP losing connectivity with the car & they were very helpful in getting me back on track.

Based on all the reports I've read, I went ahead and ordered an Accessport today. It's the weekend and Monday is a holiday so it'll be a short while before it shows up but I'll come back with my comments after I install and use it for a few days.

My Accessport showed up today, so a I did a quick install of the manager software, checked for updates, and generally poked around with it. Installation really is as simple as the videos would have you believe -- hook the car up to a charger, turn off the headlights and a/c, plug the Accessport into the OBD port and turn the key to On. A click to "install" the AP, then select the map I want (91 octane matches the gas I can get around here) and let it do its thing for 5-7 minutes. And oh, watch the Christmas tree of warning messages you'd never expect to ever see pop up on the car's MFD while the ECU is being flashed. That's a normal thing and not something to be worried about.
I've only had a chance to make a quick trip but so far the car feels much more eager. And the range remaining on my gas gauge is dropping like a rock but that's probably my right foot's fault. No drivability issues so far, but then I haven't had enough clear road to really floor it yet. I'll come back in another day or two with more thorough thoughts.

Ive had a cobb on my 16 turbo since about 2k miles. Wish there was a tune to incorporate my catless DPs as the car is very jumpy and behaves strangely under full throttle.
Watching the boost gauge it seems like the turboes spike to 23PSI and fall off from there, as if the car could use much larger turboes. And in the cold the car freaks out and doesnt know what to do under anything over 50% throttle.

I haven't tried Sport+ yet, but in normal and Sport mode my Macan seems quite happy with the new ECU flash. It's definitely a lot faster than stock.

It's only been a day, but I haven't seen anything like this with my car. I've done some short trips and freeway cruising now without issue. How cold are you talking about? It's in the low 30s here and I don't have the issues you seem to have. Are you using the latest maps? Also, I'm using the tune for 91 octane right now even though the Chevron near me sells 93.

The Accessport is an awesome device - aside from the noticeable performance gain and overall driveability improvements, you can pull codes, data log, and also features head up gauges and a full performance suite (0-60, 60ft, ET's etc). Very easy to use and we've had great feedback on them.

Of course, I can't make any promises on PCNA's behalf but they don't seem to get upset about gentle modifications imho. The only pushback I got was a suggestion that if I was going to be spending time at the track wouldn't I like to buy a GT3?

I haven't noticed this. If you're giving smooth throttle inputs, the car drives just fine. It's not until you lean into the throttle that you really notice a change with this tune. Now I may have discovered a quirk when you're driving at freeway speeds and slowly lean into the throttle but I need more time to decide if the issue isn't just with me.

Ok, it's been a few more weeks and here are my thoughts.
1: My car hasn't blown up. Always a good thing and a worry for modifying an expensive item.
2: Lay into the throttle, and the car takes off like a scalded cat. There's a slightly longer than normal hesitation as the car figures out just how to satisfy your need for speed, though. The factory programming felt better at noticing an unexpected need to accelerate (say, switching lanes in a tight traffic situation).
3: The engine and transmission are kinda schizophrenic. The engine wants to burn gas and make power. The transmission wants to stay in a high gear and be fuel efficient. The normal factory tune strikes a better balance between these two. It really should kick down a gear or two rather than just trying to power through being on the downside of the torque curve. Mostly noticeable when you're only pushing <70% throttle or so. Probably related to what I noted above.
4: Gas mileage. Yeah lost a little, but that wasn't unexpected. Mashing the gas is so much fun I don't care. It's not that bad when I get a chance to cruise at highway speeds, but that's rare for my commutes.
I'm not unhappy with the changes; they're all things I can adapt to. A little tweaking on the PDK side of things would be welcome, though.
