For Years RPM MOTORSPORT LTD. has been tuning ECU's for customers worldwide, however those customers were companies rather than idviduals. RPM would discover the technology and partner up with companies to help make the Maps etc.

in 2016 RPM's Managment decided Not to Re-New their non-compete agreements and continue to Tune DME's to Individual Customers, Independent Shops and Tuning Companies.

We are focusing on Stock-Engines to make it simple, however Custom tunes are also availalbe upon request by Adding what you need in the "Special Instuction/Comments Box" If you need more than 250 words, you may email or open a ticket to your existing order.
