Daily Light – This is your ‘stock’ power calibration to tame down your injectors and run with stock like driving manners.
No Start – This Calibration Will keep your engine from starting by turning off fuel, your truck will not start in this file but will run Like Stock if switched to this position after the truck is already running.
High Idle – This Calibration Holds the engine speed to your desired RPM for warm-up, AC, Inverter use, etc.
Quiet Idle– This Calibration Lowers your idle RPM, Injection pressure and Pulls timing at idle to produce the quietest idle possible.
Daily Driver – This Calibration is extremely clean with lowered shift points and pressures for smooth operation but offers a responsive pedal and some pep if you need it. We typically see the best fuel mileage from this file.
Heavy Tow – This calibration offers the best shifting and torque converter lockup possible for towing and keeps EGTs in check for any load. Perfect for towing up to the max tow rating of your truck.
Medium Tow - This calibration offers the best shifting and torque converter lockup possible for towing and keeps EGTs in check for any load. Perfect for towing Larger boats, Small fifth wheels or similar.
Light Tow – This calibration holds the same transmission strategies as the other tow tunes but with more aggressive fueling and is best suited for towing small trailers or bed loaded campers.
Street Shredder – Now we start having fun. This calibration is more aggressive than the daily at lower throttle input, shift points are higher to keep you in the powerband, and at high throttle input the torque converter will lock up in second gear to get all your newfound power to the ground. This file is aggressive but still very clean and daily drivable.
Cummins Killer – This is your all out, empty the injectors and race a ricer file. Great for the drag strip and dyno. This one will smoke and is extremely aggressive.
Cummins Killer Lope – This calibration is the same as your regular Cummins Killer file but will lope at idle.
These tunes are the real deal. They bring out the best of my stock 2002 7.3 f250 truck from pulling a loaded trailer, getting the best mpg in town, to seeing just what she’s got with their hot tunes. 1023 has their ducks in a row when it comes to these tunes from transmission shift strategies to power and performance. And they are always there to talk to and help with questions and revisions.
