Spring is here, and you know what that means… It’s time for tuning your diesel. Okay, anytime is a good time to tune, but right now, Calibrated Power is making it more affordable than ever. Calibrated Power is having a Spring Super Sale and that means you can add towing and performance tunes to your Power Stroke, Duramax, or Cummins engine without breaking the bank. This “tuning” sale will run from March 1 through March 31, and during this time you will be able to take advantage of these huge discounts.

Let’s start by telling you about the 15-percent off deal offered for EFILive, EZ Lynk, and MM3 custom tuning. Purchase any qualifying tune, and save money while you make your truck even better. You can check out the deals right here.

Next up is something you Power Stroke owners can really use, the Black Box. Add power and keep your emissions intact with this complete tuning package that includes ECM and TCM tuning. This device gets rid of the factory dead pedal, gives you more usable power, and dramatically improves your overall driving experience. Unlike pressure boxes and pedal-signal interceptors, this custom tuning recalibrates your entire engine operation to run more efficiently and produce more power.

The Black Box On-The-Fly Tuning features five ECM tunes that are optimized for specific driving situations.

Finally, we need to let you L5P Duramax owners know about the 20 percent off you can get when you purchase Calibrated Power’s L5P Tuning Calibration. You know you want to boost the performance of the L5P up to 595 horsepower and 1180 lb-ft of torque, and who wouldn’t? Keep in mind, this discount applies only to the cost of tuning for L5P tuning calibration.

But this sale is not only about diesel tuning. Do you want a turbo or transmission upgrade? Calibrated Power is also offering 10 percent off select Stealth turbochargers, and 10 percent off six-speed conversion kits for LB7 and LLY with transmission tuning. Finally, you can take $500 off any LB7 and LLY pre-built six-speed transmission. This includes both DT550 and DT750 transmissions.
