Supreme Service

Call 1-855-326-8863 for information or technical assistance.

At J-Ball Electronics Supreme Service is our commitment to be your trusted partner in the diesel ECM tuning industry. We know time is money and we know how important it is that your equipment is out working, not sitting in a shop with problems.

Having started in the trucking industry over 50 years ago, we understand the struggle that truckers and other heavy equipment owners (farmers, loggers, road builders, pipeliners, miners, oilpatch and construction companies and others) face with ever-increasing costs cutting into the bottom line. Our products and services are all designed to provide owner/operators, businesses owners and fleets with diagnostic tools and ECM tuning solutions that save money day after day.

A critical part of our commitment to you is our technical support team, available toll-free at 1-855-326-8863 from 6:00am to 4:30pm Pacific (9:00am to 7:30pm Eastern) Monday to Friday to answer questions and help troubleshoot any problems you may encounter.

J-Ball Tuning is covered by a 1 year warranty (3 years when part of a tuning bundle), click here for more information on the J-Ball Electronics Warranty.
