Fixed some issues with processing tunes.

User reviews

Don’t use this app yet.

Using the app crashed my device, I’ve also read that other users have experienced the same problem. But I can say that HP Tuners have responded and are actively taking care of the issue.

Response from developer

Sorry to hear you are having troubles with the ap. In version 2.1.4 updates were included to alleviate crashing events reported by some users. If you can provide an Infolog for tech support (tools>help>gather Infolog for support) we can look further into this issue. If you can also provide details on the actions you were performing when the crash occurred that will be helpful as well. Please include your nickname from this review in the support request to ensure we can correlate you issue with this submission

The Worst Part of My Job

If I could give 0 stars I would. It’s unbelievable to me that HP Tuners forces me to use TDN to tune some car combos and it just doesn’t work more than half the time. On top of that they have the slowest support system ever, I opened a ticket 14 days ago and have gotten 2 replies, both asking for info I provided when I originally opened the ticket. I never write reviews for anything but it’s honestly that bad.
