Dragy GPS Performance Box OBD-II

Dragy GPS Performance Meter: Prove Your Gains

Seat-of-the-pants feel is great, but numbers settle arguments. The Dragy turns your phone into a professional-grade performance meter, using high-speed satellite GPS to time your truck or RV’s acceleration down to the hundredth of a second. It’s the same kind of data serious tuners use to validate results on the street, without the cost of a dyno session.

Run it before your tune and after, and see exactly what you gained. Track 0–60, 60–130, eighth mile, quarter mile, half mile, braking distances, and custom speed windows you set yourself. For truck and RV owners, that means real proof of improved passing power, merging confidence, and towing performance where it actually matters: on the road.

Why you’ll love it:

Lab-level accuracy in your pocket. Multi-constellation GPS delivers precise, repeatable timing with automatic slope correction on every timeslip.
Zero installation. Charge it, pair it to your phone over Bluetooth, set it on the dash, and go. No wiring, no tools.
Works alongside your tuning apps. Runs at the same time as other Bluetooth apps, so you can log performance and monitor your tune together.
Share and compare. Save your runs, overlay data on video, post timeslips to social media, and see how you stack up on the Dragy leaderboard.
All-day battery. Long-lasting built-in battery means it’s ready whenever you are, and it tucks into the glovebox when you’re done.
Fits anything. Universal design works on any make and model, from daily drivers to diesel pushers.

Free Dragy app available for iOS and Android.

Pair it with a 5 Star Tuning tune and see the difference for yourself.
