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. |
So how does this compare to something like JB4?
