H&S Performance Overdrive Transmission Software 111007

The 5.9 Overdrive software includes a modified torque converter lock/unlock strategies that will command the TC to lock in 3rd gear under wide open throttle and hold it locked through 4th gear. Shift points are also modified to take advantage of the available HP and torque output. On a stock 2006 Cummins, we have shown a 0.2 to 0.3 second quicker 1/4 mile times JUST from the addition of the H&S “Overdrive” tuning. Light throttle torque converter strategies have also changed to lock-up sooner, keeping more power directed to the road instead of wasted in heat and friction.

Black Maxx, Mini Maxx, and XRT Pro owners will have the ability to use their existing units to load the H&S Overdrive Transmission software. Using the H&S downloads section, you will simply update your tuner (Black Maxx or Mini Maxx) to the latest software level. Once the tuner is updated, the transmission tuning software is ready to be unlocked. Once this software is purchased, you will receive an e-mail from H&S Performance within 1 business day containing your H&S Overdrive Unlock Code. If you have not received your unlock code within 24 hours after purchase, please contact XDP customer service.
