Collection: HP Tuners

HP Tuners is the gold standard in automotive diagnostic and calibration technology — and at Dieselr, we choose every tool, cable, and accessory you need to do it right.

This collection includes our range of HP Tuners compatible products, from the powerful MPVI3 interface for compatible ECM or TCM ,  credits, and essentials for serious tuning. Whether you're tuning a 6.7L Powerstroke, an L5P Duramax, or a 6.7L Cummins, you’ll find the HP Tuners tools trusted by professionals and shops across North America.

Every item here has been tested and recommended by Dieselr’s in-house mechanics and tuners. We don’t stock shelf-fillers — we only sell parts we use on our own trucks. HP Tuners Dieselr customers also get access to real human support. No bots. No forums. Just real answers from actual techs who tune and calibrate daily.

Looking to read, write, or data log? Start with the MPVI3 and pair it with tuning credits based on your truck. Need a pro tune file? We offer those too.

Get your HP Tuners products from Dieselr and stop guessing.
