I just ordered a 5Star. Arrives Monday.
For my 2014 Focus though lol.

I hve have no idea how to use it or anything about it. Except that they said it will fix my shifts.

i loaded and ran the 87Performance tune today. It was definitely excessive
It was too high of rpm at all times. At ALL times : no need for 3,000+ rpm rolling through a parking lot.
It had more power for sure but that’s not why I bought it. And It had a more aggressive full throttle launch from zero.

I didn’t notice an increase during the middle of the tachometer, but maybe it was better.
I did notice a high rpm surge of power at the top of the tach that induced (previously nonexistent) torque steer - so I suppose that’s definitely a marked increase.

I then switched to 87 economy (I think; see next sentence) and it was also excessive. So much that I wondered if I had successfully switched tunes or not. It was still running higher rpm than usual.

In all honesty it was disappointment so far: but only in a way that it did more than I wanted it to do, while not improving the issue I asked for (quicker/firmer shifts)

My largest disappointment is that I was expecting to be able to switch tunes “on the fly”, but it’s actually about 10-15 minute process, and the vehicle must be parked and not running.
Man I just want it to be docile and quiet and friendly under light throttle (with quicker shifts), and then get powerful as I dig in with my right foot. I don’t want to have to park and wait.

i guess if they tuned my 2.0L four cylinder this much; maybe the product is even more impressive with a 6.8liter V10.

The return policy is pretty crappy, so if I don’t like it on my Focus then im praying they’ll reprogram it for my V10.

Overall; I’m quite impressed with what they produced; but it doesn’t match the milder desires I spoke about to them. Maybe they’ll retune it and I’ll be happy. (And then buy another one after my v10 is reassembled).
Ill keep everyone posted.
