Thank you for choosing Double R Diesel for your Diesel Performance needs. We have decided to make this Q&A to answer some of the basic questions the newcomer may have and hopefully steer them in the right direction of purchasing the MM3 Tuner. *Please note: We do not offer tuning for EFI Live, EZ Lynk, H&S Mini Maxx or MCC Tuning anymore.
The picture above or the link below will direct you to the page on our website with all the information for the newcomer to the Cummins 6.7L Diesel Performance World to read.
The reason we're not posting all the information here is over time the information may change or could change and we only want to have it in one place that we have to update.
