Safe & Reliable 6.4L Tuning From 5 Star: While there may be other companies that push the boundaries of 6.4L diesel performance, you can be certain that 5 Star Tuning puts safety above all else. Whether you're running the Transmission, Towing or Performance tune, each has been created specifically to give your Super Duty the ultimate in driveability, fuel economy, horsepower and torque while keeping your engine safe from getting damaged. 5 Star Tuning is so confident in their custom tunes that they will keep tweaking your tune until they get it right or guarantee a full refund if you're not satisfied.
5 Star Super Duty 6.4L Custom Tuning Process: After you order your tuner, within one business day, we send you an email with tuning information that we require for your truck. If you don't receive an email, please check your spam/junk folders. After you completely fill out your tuning information, send it back to [email protected]. We'll then forward the information to 5 Star Tuning who will write your tunes and upload them onto your tuner. Your tuner and tunes will be shipped out roughly one business day only after we've received your completed tune form. After your tuner arrives, you can upload your choice of tune to your truck. If you have any further questions, please contact us directly at 623-434-5277.
Tuning and your Powertrain Warranty: any aftermarket PCM/ECU tuning can absolutely result in Powertrain repairs not being covered under your manufacturer's warranty, making it effectively voided. Please take a look at Stage 3's Stance on Tuning and Warranties or call us directly at 623-434-5277.
