7.3L Powerstroke Custom Tuning

Why can't I select the custom tunes I want?

As of September 2021, 1023 Diesel & Fleet Inc. discontinued all calibration options we considered to be a nuisance, or unnecessary, or undesirable in target markets. We reduced the set to 6 calibrations for manual transmissions and 7 for automatic. This means lope idle, quite idle, and all random high idle options, were removed. The Ludacris calibration was also discontinued, as we were never happy with its design and intended use case and it limited our ability to move forward with emissions compliance.  

How do I find my PHP Hydra Chip serial number?

I received my tuning via email and I already had a PHP Hydra Chip or SCT tuning device now what?

The email you received with your custom tuning includes instructions on how to move forward. If you have a PHP Hydra Chip and received an email including tuning for your chip, you should see a link for the Hydra Flash software and information page, which will include the download and links for information on how to load your custom calibrations. If you have an SCT device, there is a link for the updater software and information on your device.

Once your tunes are loaded, follow the rest of the instructions we have listed pertaining revision policy, and minimal drive time.

Please email or call if you are still having issues.

I loaded your tuning and my vehicle is still having ‘X’ issue.

If your vehicle previously had an issue and is still having an issue it likely not tuning related. Please look into scanning/data-logging equipment to further diagnose what the issue with your vehicle could be. If you need assistance, we would be happy to help.

Transmission slipping?

When it comes to 4R100 and E4OD transmissions and slipping, without going into depth, tuning is almost never a direct cause of slippage. These transmissions are mechanically controlled and electronically trimmed. If you loaded tuning to your truck and your transmission starts to slip during shifts there is nothing we can or will do to keep your transmission from slipping. Having firmer shifts is always desired for making your friction disks last longer with increased torque, but we cannot make ANY guarantees that your transmission will last any longer with added power.

Really under-powered compared to other tuning or stock tuning?

If your vehicle is severely under-powered compared to stock or other tuning right from the start, we ask that you start with the basics. We reference the MAP sensor to help control maximum fuel allowed at a given rpm. If your map sensor, hose, or electrical connection are not ideal, then it could be causing an issue with our fueling control. The best way to figure this out, is compare your MAP sensor input with a logging device to a mechanical gauge. IF you found your readings to be correct and you are still having issues, then get in touch via the revision form and we will work quickly to adjust to your diving style.

Torque converter lockup or overdrive?

When requesting revisions, it is common for customers to get confused describing torque converter lockup or overdrive up-shift. The easiest way to describe the difference, is to push the Overdrive Off button and if the shift you are referring to is the last shift you feel, it is torque converter lockup. Just in general, we typically lock the TCC in 3rd gear unless you are at full pedal in 2nd gear we may lock the converter.

To break it down, your 4R100 and E4OD automatic transmission up-shifts go: 1->2, 2->3, Lockup, 3(locked)-> Overdrive (4th gear).

I have an Excursion and the truck won't start in the tunes you sent me. (PATs)

If you have an 7.3L Excursion truck and the engine wont start in the new tunes ONLY, chances are it is a PATS issue. PATS is the Passive Anti-Theft System and if not configured correctly the engine might not start. This is usually caused by the incorrect PATS configuration when loading the tunes to the Hydra Chip. The images below show the location and configuration of the PATS system when loading tunes to your Hydra Chip with Hydra Flash. If you choose not to use PATS with your excursion you must disable the module, we will not discuss this, but it is an option and sometimes the only option. While it happens it is usually slim, on occasion a tune sent for your vehicle might not have been updated to support PATS and must be changed. If you have gone through unloading and reprogramming your hydra chip with PATS supported and it is still having no-start conditions please contact us through the support page.


My PHP Hydra Chip has 17 positions, can I use all of them?

The PHP Hydra Chip only has 15 user programmable positions. The other 2 are the 00 Bypass mode and the NS No Start mode.

These modes plus your 15 tune positions add up to the 17 positions that most people talk about:

High EGTs?

First let's define high EGTs. 7.3L Powerstroke Diesel engines can handle short sustained exhaust temperatures of 1250 degrees F. If you aren't seeing temperatures this high, you don't have anything to worry about.

Often customers that are experiencing high exhaust temperatures, their first reaction is to call us, their tuner. We usually respond with "We need you to do a boost leak pressure test, and a thorough visual inspection of your turbo charger up-pipes. Often customers have large boost leaks or exhaust leaks that can cause high exhaust temperatures and this must be address.These leaks are often associated with exhaust smoke.

Do the EGT issues happen when the engine is under 1700 rpm? If you have an automatic transmission, we can downshift or unlock your torque converter to help get your RPM up higher, where the engine can make power more efficiently and this will help keep EGTs down. If you have a manual transmission, frankly we suggest you downshift if you are in a low rpm situation like this.

If you have pressure tested your CAC system and you cannot see any exhaust leaks, you should be looking further into your turbo health and turbo/injector combination. We say this for the simple fact, that as your tuner we can't do anything special to reduce your exhaust temperatures. The ONLY thing we can do is reduce power. By doing this, it often causes shift point and shift firmness inconsistencies, so when we say "just let out of this pedal" it's not because we don't want to help you, it's because it usually causes more issues than it solves!

What is the difference between Cummins Killer and Ludacris (Discontinued)?

In short, Ludacris and Cummins Killer will make the same power on a dyno, however the Ludacris will give you that power at a lower pedal position. Ludacris is a further unregulated version of the Cummins Killer, meaning it will be less "street-friendly" than the Cummins Killer. Ludacris may also carry more risk of engine damage as it allows all of the fueling control up to the driver and their right foot.
