The numbers and their respective dynographs for the stock tune and our premium gas tune options are below:

-Stock = 221whp / 231wtq

-91 oct WW 7.0 = 224whp / 253wtq

-91 oct AD 7.0 = 225whp / 254wtq

 

*Elevation: ~4000ft above sea level

*Rule of thumb is to expect power loss of ~3% per 1000ft of elevation, so theoretically you could calculate ~12% loss vs sea level, although that might be a bit ambitious... nonetheless, the elevation gain should be noted when comparing our regular and premium fuel dyno results

 

*All tunes including the OEM CAL were run with 91 octane.

*Truck was stock with 32" tires (half-inch taller than stock)

*Smoothing of SAE 5We're very excited about these torque numbers and that curve demonstrated in the dynographs.

 

When looking at these results, we can demonstrate a strong torque curve while still pulling strongly in the top end, consistent through the pull. At 4000rpm, a wheel-torque increase of 37-38 ft-lbs (WW vs AD) is observed over the stock calibration, which is what those arrows in the first two dynographs are pointing out.Our premium fuel tune does not seek out peak power either, because drivability aspects could suffer and drivability with a strong, consistent, dependable tune is the primary goal for our YW tunes. You can have potentially higher power numbers but on a tune that may perform at a sub-standard level. Peak numbers simply for the sake of bragging rights shouldn't be the goal if your drivability suffers as a consequence.The YotaWerx Tuning WeekendWarrior v7.0 and ActiveDuty v7.1 tunes for both regular and premium octanes are considered to be finalized tunes at this time. More Info ...
