AISIN (FYI)
The Aisin transmission is most often (but not always) found in the 2013-2021 HD Cummins Cab & Chassis pick-up truck models. It was an available option for standard pick-ups as well but, came with a price tag. Your Aisin equipped Cummins already has more power than 68RFE trucks. With custom engine tuning it will run better than it ever has before, however at this time there is no transmission tuning available. Our engine tuning for your truck is specifically optimized to achieve maximum performance with your specific transmission. Others may run a 1-size-fits-all when it comes to 6.7L Cummins engine tuning, but if you have an Aisin transmission the difference between a 1 size fits all and a custom engine tune is significant. 

G56 (Manual Transmission)
The G56 Manual transmission is offered through to the 2018 model year. The factory clutch can handle a reasonable amount of added torque with an adult driver at the wheel. For these trucks, you get all five Custom Engine Tunes in individual files. Our Engine tuning for these trucks takes into account the difference in engine operation for manual transmission trucks to provide you with peak performance for your specific drive train.
