MHD Flasher N54 Customer Insights

1. When I tell people about being able to literally flash my car or install a new tune all from my cell phone, they are blown away.

2. Easy flash tunes, easy connection, and the best part is that it only takes a few minutes to flash a tune.

3. Consider full battery registration (different brand batteries).The exhaust burble doesn't work 100% on stock AT vehicles due to the cats and muffler.

4. The program and tunes have been able to adjust each step as I made my way from stock to FBO.

5. it's very convenient to be able to load maps from your phone as opposed to having an additional box and cable hanging around.

6. Upgraded clutch highly recommended with the flash.I love that this team works hard to give us SAFE, STABLE upgrades.

7. The customer support was difficult to find at first, but I see they are quick to respond to concerns in this comment section.

8. Stock clutch with 100k miles didn't like the tune, but probably needed to be replaced/upgraded anyway.

9. I give them a high star rating because they are responsive and are one of the few organizations that care to help you diagnose issues the app and find a solution.

10. The ability to fine tune certain items was amazing too.

11. First flash takes ~40 min over WiFi, subsequent flashes take about ~2 min.
