Customizable DSP5 ECM & TCM

If you like the idea of custom tuning but don't want to get involved with the programming or software end of it all this package is for you. Our ECM and TCM package comes complete with 5 tunes plus TCM tuning. We strongly recommend TCM tuning for all trucks and will significantly increase drive-ability. ECM's and TCM's can be shipped to us for 'Bench Flashing', where the customer removes the ECM/TCM and mails it to us for custom tuning or we can send them to you at an additional charge. Simply send us back your ECM/TCM in working order within 10 days and receive a full refund.

Tunes can be written to any power level and to compliment any combination of performance parts.

Our goal at Duramaxtuner.com is to produce healthy trucks and happy customers.
