I owned the HPP for a little over a year. During that time I had a Cobb tuner and Livernois tuner and did multiple comparisons. I found the ots tune from Livernois to be far more refined than the Cobb ots tunes. The only benefit of the Cobb is the ability to do a remote pro tune but if your strictly comparing ots tunes, Livernois has the upper hand.does anyone here have the livernois Tune?
I no longer have the HPP edition. I accepted an offer from Carmax to purchase the car for more than I originally paid for it. I currently own a 2021 Mustang base model. I have already tried the Cobb, SCT, and Livernois ots tunes on my new mustang. On the base model, the SCT ots tune comes out on top, followed by the Livernois ots tune, followed lastly by the Cobb ots tunes. Heck, Cobb even used my vehicle in Austin for their implementation testing of the 2021 model year. After they were finished they gave me the beta version of the stage 2 map for the 2021 year. Overall feel and drivability was poor. They had me datalog my results and sent me a revision which made minor differences. The "specialist" acknowledged the issues and admitted Ford made changes to the 2021 year. It sounds like they were trying to heavily rely on previous year ots tunes instead of creating new tunes. They ended up releasing the 2021 option regardless of the drivability issues. I ended up selling my Cobb tuner. Their rhetoric of releasing "unpolished" products put a bad taste in my mouth.
On side note, I really enjoy the SCT ots tune but they are working out a glitch for the 2021 models. The speed limiter is still in place regardless of the SCT tuner saying the limiter has been removed.
