Want the best and most reliable tuning for your 2020+ 6.7L Super Duty?

Areas We Address

IF you feel you don’t have all the Torque that your 6.7L should have come with from Ford?  Or maybe your 6.7L seems a little Sluggish? We can help! We have taken the same 5 Star approach with the 6.7L Diesel as we have done with other vehicles in the past. Our tuning goals for the 6.7L have been really simple, focus on good safe reliable power , good drive ability and finally maintain or increase efficiency. We also practice what we preach at 5 Star using our own 6.7L diesel working our calibrations in the Real World. Taking this approach ensures that your tuned 6.7L diesel provides you a long service life .

The 6.7L diesel can suffer from poor throttle response down low. In fact the factory programming has limits on torque allowed at certain throttle positions. By addressing this issue and a few others; improvements will be much better throttle response, step on go pedal, vehicle will respond quicker…this DBW system is a torque driven system, it works by taking a certain amount of torque via engine and wheel and applies it to what the driver foot say it needs; a better way to explain it is its a torque limiter. It only allows so much torque at a given pedal position. Stock tables are conservative and numb at best and that’s why one would feel some times a lag or a goofy pedal with DBW systems. For a 6.7L this is one of the most critical areas that must be addressed and modified to generate more torque /hp and throttle response. By reworking the OEM strategies makes your 6.7L come to life!

The 10 speed transmission that comes standard with the F250- F350 6.7L is a big improvement in driver controls over prior 6 speed transmissions. However, there are still some significant benefits to be had re-calibrating normal daily shift strategies. With the 2020 having many modes, we will just talk about the 2 most used modes here.

DAILY MODE    We have noticed that while in normal everyday mode that the transmission will move into 8th,9th, 10th gears really quickly around town with speeds as low as 42 mph this really lugs the engine and when trying to accelerate there is a pretty good delay to either downshift or accelerate. Also Ford is skip shifting in normal mode as well.  We can correct this by moving some shift strategies patterns around in all gears. Our calibrations will have emphasis on shifting at the right mph and rpm as to take advantage of the low torque that is available from the 6.7L while maintaining great fuel economy and power to accelerate when needed.

TOW/HAUL Mode   Coasting or slowing down the downshifts don’t command soon enough to keep the RPM’s up in torque range and when back in throttle multiple downshifts may occur. so a quick downshift for braking is required for owners that are going to tow heavy. We have re-calibrated tow/haul mode strategies that enhances keeping the engine RPM’s elevated to take advantage of the torque band which will require less downshifting by optimizing gears. We have also enhanced the down shift patterns to allow better engine braking with this V8 engine. All of our calibrations have this new tow/haul strategy except performance calibrations.

5 Star Tuning will be offering 4 popular tuning choices for the new 2020 SD 6.7L diesel.

5 Star Calibrations will have all the enhancements completed in Engine and Transmission functions. This includes Drive By Wire, Fuel, Shifting, and Torque Converter strategies. These calibrations can increase economy the trick is staying off the go pedal.

At the time of your order if your ECU strategy code is known, we will send your tuner loaded with tunes on your selected tuner. If this information is not known at the time your order is placed you will be provided a blank tuner to acquire the needed vehicle information.

Where do I find my ECU Strategy Code?

If using an SCT or Bully Dog Device: On your device under vehicle information, you will find your ECU Strategy Code. An example of an ECU Strategy Code is PKRK0R2.

Note: If your vehicle is a 2015+ we will also need your ECU SWPN (HL3A-14C204-BPH). For diesel applications we will also need your TCU Strategy (TPCL0HH) and TCU SWPN (HL3A-14C337-HH) in addition to your ECU Strategy and ECU SWPN.

If using an HP nGauge: Plug your nGauge into the OBD2 port the vehicle you intend to tune. Use the menu on your device to select TUNING, then proceed to select the PCM type and choose READ VEHICLE. Upon selecting “read” you will see a variety of vehicle options. Select your application vehicle such as: “2017 F150 Ecoboost 3.5L GTDI V6: PCM + TCM” “TC-277A 4M+TCM.”
