Calibrations

• Stock Optimized (+0 HP)
• Heavy Tow (+12 HP)
• Light Tow (+24 HP)
• Sport (+36 HP)
• Performance (+48 HP)
• Race (+60 HP)
  

Engine Calibration

• Increased throttle response (reduced or elimination of dead pedal)
• Increased torque in all power levels which allows earlier shifts when applicable for improved fuel economy
• Increased fuel economy due to optimal commanded fuel quantity, injection events, timing, and trans calibration
• Quicker response to driver input due to transient fuel, timing, VGT and Transmission calibration
• All safe non aggressive OEM detune / back down strategies are left intact or calibrated for the higher power levels that prevent premature failures
• All limiters that are safe to be removed are
• Exhaust brake memory and maximized exhaust brake
• Removal of auto start and stop as well as idle timers
• Tire sized changed and if opted for transmission calibration it is optimized for specific tire size / gear ratios

Transmission Calibration

• Extended transmission life, increased fuel economy, and better driving experience
• Increased line pressure and shift parameters that would reduce shift times, slip etc follow actual torque models in ECM and TCM
• This strategy increases fuel milage, reduces duty cycle wear, eliminates harsh or random inconsistent shifts or characteristics that do not match the drivers request, input or desired feel
• This is why it is important the engine calibration be done correct or our transmission calibrations be paired with our engine calibrations as the models have to mimic each other
• All calibrations match the increased torque as well as earlier torque to apply it most efficiently
• Refined shift points to get rid of the low rpm lazy feel at low driver inputs cruising or towing waiting on the turbo to spool that usually results in a lot of pedal travel and down shift
• Tire size, gearing, and larger turbos this is a must to tailor to that specific mod
• Earlier converter lock up to use increased torque & increase fuel milage as well as reduce temps
• Earlier unlock & downshift eliminates lag from time of driver input to acceleration
• Torque converter OEM partial lock or locked shifts to remove flare feel during shifts
• TC feel can be stock or increased for less slip to lock time in 2-10 gears
• Full manual control over shifts in driver select mode
• Aftermarket valve body recommend for calibrations above heavy tow
• Since hydraulic pressure is directly related to your clutch holding power we do not recommend tuning over heavy tow without an aftermarket valve body
