Straightforward Reliability

The Mini Maxx V1 is perfect if you want simple, no-frills deletes on pre-2020 rigs. Plug it in and its pre-loaded tunes clear out the DPF/EGR without tripping check-engine lights. The color display is clear and shows boost, EGTs and codes in real time. It won’t wirelessly update and it doesn’t support the newest trucks but for 2003-2019 models it’s rock solid.

  • Shift-on-the-Fly Tuning
  • Deletes DPF/DEF/EGR Systems
  • 20 + Digital Engine Gauges
  • SD-card/USB firmware updates
  • Up to +250 HP* Potential

Delete-and-Dash Specialist

If you work on Ford and GM diesels, the Mini Maxx V2 steps it up with a sharper screen and claimed 3–5 MPG gains after deletes. It handles most older trucks without fuss but watch out on 2019+ Rams (capped boost) and LML Duramax (wonky readings). No Bluetooth but if you value simplicity, it gets the job done—just double-check compatibility first.

  • Built-in Wi-Fi hotspot
  • Cloud-delivered tunes & OTA updates
  • Live data on iOS/Android app

Wireless Convenience

This one shines on 2017 and newer trucks. With cloud-based tuning via your phone, it’s idiot-proof for emissions deletes. Universal OBDII fitment makes it easy to swap between rigs, and automatic updates keep it fresh. You won’t get deep custom tunes without buying extras, but for quick, wireless deletions it’s hard to beat.

Shop-Grade Flexibility

For guys who love to tinker, the AutoCal V3 is a dream. You can craft custom tunes, log data, and swap between multiple vehicles. It takes patience to learn, but for shops or fleet owners who need ultimate control, it pays off. Just know it’s more of a project tool than a plug-and-play gadget.

Cummins-Only Powerhouse

This is for the die-hard Cummins crowd. The CTi delivers dyno-tested power and efficiency gains, and it’s built like a tank. At $3,500, it’s overkill for weekend warriors but if you haul heavy loads daily and live off horsepower, it’s worth every penny. Otherwise, you’ll find simpler and cheaper options.

Warranty-Dodger’s Tool

Made for 6.0 L, 6.4 L, and 6.7 L Powerstrokes, this unit removes factory limits, sharpens turbo response, and even erases transmission lag. Its “stock restore” hides the tune from dealer scanners, so you keep your warranty intact. It’s a bit spendy, but if you own a Ford and crave smooth, reliable power, it delivers.

OBD2 Flash Tuning Device

  • Universal OBDII compatibility
  • Pre-loaded performance maps
  • Stand-alone Data Logging Mode

Budget MVP

Need a starter tuner? This pocket rocket adds a pep to daily drives without deletes. Universal OBDII compatibility and quick flashes mean you’re up and running in minutes. It won’t rival the high-end units, but at under $400 it’s the easiest way to taste performance tuning.

Final Thoughts

Every truck and every driver has its own needs. For no-nonsense deletes on older models, the Mini Maxx V1 is hard to beat. If you want wireless ease try the Ez Lynk. Gearheads who love deep control will appreciate the EFILive AutoCal. And if you haul heavy with a Cummins, the CTi is a beast. Pick the one that fits your rig and hit the road with confidence.
