Thread: 1st gear shifting early?

I'd think so, but an aftermarket exhaust that accounts for the way the current exhaust system is set up....well, I don't know if it exists here right now. That's why I was hoping Alex would look into it.

I picked up the car this morning, and I thought I'd share the notes on the tech sheet. I think there's some good solid information for all of us, regarding regen, backpressure, etc.

Also, the car is running amazingly well. Better than I've felt in a long time. My guess is that the DPF has been sooted up for a bit, and it just continued to build up, causing the eventual degradation of performance. Both stock and tuned, the car is even more fun to drive than I've remembered in a while.

Far from an ideal launch (I let it shift at it's programmed max for a reason....ideal shifts are closer to 4k), but this is today, as compared to before:

FYI, the car is back at the dealership, with exhaust pressure error codes. This started happening within a week of returning it. I'm hoping it's just a bad new DPF. I've run the car an extended period of time at a static rate of speed on the highway for an hour in an effort to force a regen, to no avail in fixing the issue.
We'll see what they have to say.
