Rip off

Total garbage product. Useless support. Stay away from the RTD, get the MPVI instead! You’ve been warned…

Terrible connection

I honestly hate this app, it’s easier to use a computer. I have sync errors 24/7, it logged me out and will not let me log back in, and I cannot upload any files. Yes it’s connected to the RTD, and yes my internet is stable. It will let me log in on the HP tuners website, but the app won’t do anything when I log in. Just keeps saying log in.

Worked great once

Worked great for 1 week. Now the app is clunky as hell and won’t connect to my tuner. Nice.
