Tuning isn’t just pumping in a bunch of numbers to make numbers on the Dyno! It’s understanding each vehicle that’s in for a tune, parts that are on the vehicle and the mechanical efficiencies that they work best at. There limitations and keeping away from diminishing returns for little power gain 💻📈

79series couldn’t hold down the torque and HP we laid into it, blowing through the upgrade clutch that’s really limited to a basic setup. We put in a NPC1300nm to get the job done and walked in 327hp / 871nm on the stock injector, HOW you ask. Watch the reel 👀

We had some of you ask do we tune NP300’s and do packages for them 🫡 YES WE DO, while we havnt posted many if any, we got this one on a silver platter for you, HUGE GAINS, HARD CUT LIMITER. Another tiny motor trying to move a big rig, 2300cc is not much to play with but we dive deep into the ECU to deliver what they needed from factory but put us in a job 🫡💻📈
