My BPM tune is installed and I'm very happy with the outcome! It cost me $1399. Definitely more power throughout all rpms and feels much faster now. No error codes or any other issues whatsoever. I will take it to the dyno and drag strip soon and share results. Communication and support through the process was excellent and Mike from BPM ensured proper installation for me. Very easy to go back to stock, it takes about 5 minutes to put it back.
Overall great product and I highly recommend it to anybody who is looking for more useable power without sacrificing drivability or reliability.
Where did you buy your BPM tune from? Still happy with it? Any track results?
Thx
I got it directly from BPM. I am super happy with Stage 1 performance. Best 0-60 was 3.58 sliding a little bit. 60-100 time was more impressive at 4.23 vs Racechip GTS black at 4.78.
Low end and mid range was much improved and you can definitely feel it every time you hit the accelerator.
I just raced and pulled on a Panamera Turbo the other day. Car really moves. On top of that I get an average of 20.4mpg daily driving it(relaxed suburban commute).
I think you'll be very happy with it.
