1023 Diesel Hydra Tunes | 6 Tunes

NOTE:  You must specify the manufacturer and build date of your current 7.3L fuel injectors if they are not factory, in the notes section of this order. We must know this information, otherwise you will receive an email asking for fuel injector information and you will experience delays. 

We do NOT support custom/home built fuel injectors without a proper flow specifications sheet and testing procedures. Without this information we cannot support revisions on your tuning and we will NOT refund the purchase if you wish to continue. If you mention your fuel injectors are custom built, please wait for an email from our tuning department asking for more information. (Expect delays)

Support starts the date of the purchase.

If you have a pre-existing "issue" prior to purchasing tuning assuming we can "fix" it, we may end support without a refund. Please see FAQ 

If you fail to bring an "issue/complaint" to the 1023 Tuning Department's attention within your 30 day support window, we are not obligated to support your "issue/complaint" or refund your purchase. 

Custom Tune Options:

Daily Light - This Is your 'stock power' calibration to tame down your injectors to run as close to stock power as possible.

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.

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. (Tow-Econ for manual transmission)

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. (Automatic transmission only, Tow-Econ for manual transmissions)

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 new found power to the ground. This file is aggressive but still very clean and daily drivable. Max HP and smoke is also going to be greatly determined by your choice and turbo in conjunction with your injectors.

Cummins Killer – This is your all out, empty the injectors and race a ricer file. Great for the drag strip and dyno. This calibration is extremely aggressive and will have some smoke output. Max HP and smoke output is also going to be greatly determined by your choice and turbo in conjunction with your injectors.

Cummins Killer Lope – This calibration is the same as your regular Cummins Killer file but will lope at idle. (99-03 trucks Only)

Ludacris –This is our most aggressive all-out tune that will make MAX power at WOT with full control over how hard it fuels. Ludacris also fuels differently in the mid range get the turbo online sooner compared to other calibrations.

Ludacris Lope – This calibration is the same as your regular Ludacris file but will lope at idle. (99-03 trucks Only)

    I got these tunes to see if they would fix some issues I was having with a high end engine swap. I had previous tunes from a well known tuner and while his dragstrip tune was awesome, his everyday tunes were giving me problems. I need to get some tires that will grip to compare the high end tunes, but the milder tunes are exactly what I wanted and a night and day improvement. I would highly recommend getting tunes from 1023 if your engine is built to handle what they throw at it!

    Hydra tunes

    Can’t believe the difference in these tunes vs the stock hydra tunes. Best $200 I’ve ever spent on my truck. I actually bought some tunes for my dad they were so good! What a difference!

    So far my truck has performed so much better with 1023diesel tuneups. Will continue to do business with these guys.

    Exceptional tuning

    Posted by Travis Jentz on Jun 1st 2020

    At first I thought maybe these weren’t the tunes for me. Then I remembered reading 1023’s note “don’t be afraid to use the pedal”. Wow, I actually had to learn how to use the pedal again after using other tuners for the last 10 years.
    At idle there’s that classic 7.3 bwah bwah bwah sound that had been over rev’d and missing. It drives stock like(with more power) until I get into the pedal then it’s just silly(perfect shifts, and definitely gets the most out of truck)
    I can’t recommend this tuner enough! You will be happy you chose 1023diesel

    Great effort and results

    1023 was the only tuning shop out of 3 I contacted that could do a decent job on my California emmisions 7.3 f250 with a rather rare pcm box code. First company didn't want to touch it. Another tuning company couldn't get rid of glow plug and ebpv issues caused by their own tunes with 5 weeks of troubleshooting. 1023 at least started off without engine codes but the throttle response and cold start smoke needed work. It took a few weeks and many emails but 1023 was determined to make it run proper with the single shot injectors. The truck now drives very well, especially the throttle response for shifting my manual trans. EGTs are in check. I'm anxious to see what mpg I get on the highway now, I can tell it is already better that the canned hydra tunes.
