My truck recently started throwing a P0430 code. When I cleared the code, it would routinely come back within one or two days. This happened across multiple tanks of fuel from different stations, so I knew that bad fuel wasn't the issue. I also know that my 25,000 mile truck has no maintenance...

Has anyone with an aftermarket tune installed on their 2021+ F150 installed OTA update PT-25.15.5 yet? Did you have any issues with your tuning device recognizing the new PCM strategy? Were you able to flash a new tune file without any issues? I'm using an HP tuners MPVI3.

I've rebuilt plenty of differentials over the years, but building one from all new parts has been very annoying and I ran into way more problems than I ever could have anticipated. First and foremost Ford's quality control is terrible, I'm used to parts missing from their ring and pinion kits...

The friction rating of brakes pads is expressed as a two-letter code where the first letter designates the normal low-temperature (200 to 400° F) friction, and the second letter designates the high-temperature (300-to-650° F) friction. SAE J866 Friction Designators C: Up to 0.15 D: Over 0.15 up...

I've been dealing with false knock on cylinders #1 and #3 for a while now, and it has been an issue both stock and tuned. It's easiest to duplicate around 2000-3000RPM at 0.3-0.6 load, but I occasionally see it at WOT too. When it occurs, I see cylinders #1 and #3 pull 3-5° of spark while the...

Earlier today I removed my front differential to install a Torsen carrier. Before pulling the differential out I knew that my pinion seal was leaking and my axle seals were weeping, but I had absolutely no noise and no reason to suspect a bearing failure. After pulling the seals out of the...

Over the weekend I finally got the chance to install my new intercooler and do some testing. The high/low numbers posted below are what I saw when starting a few seconds before the WOT pull section of the datalogs and ending a few seconds after the WOT pull. Both WOT pulls were started in 2nd...

Now that my PCM has been unlocked by HP tuners, I'm debating whether or not I should try tuning my truck myself and I’m wondering if anyone here can offer some advice based on their experience. I’m not new to tuning, but my experience is very limited. I have some experience with older Holley...

Initial Testing I recently added a FactionFab resonator delete pipe to my truck, and before I installed it, I decided to weld in an O2 sensor bung about 6" back from the flange so I could easily measure the back pressure in the system. I did this because I wanted to determine if there were any...

Now that my F150 is 2 years old it was time to change my brake fluid and as many other people may have noticed, the procedures for doing brake system maintenance and repairs on the 2021+ F150 have changed from earlier model years. Our trucks need to be put into brake maintenance mode anytime you...

I recently ordered a second PCM for my truck so that I can send it off to HP tuners to have it unlocked for tuning. I have to program the module before sending it to HP tuners and I'm wondering if it's possible to have two PCMs programmed to the same truck that are essentially identical from a...

A few months back, I noticed some odd behavior from my IPC after an OTA update. The cluster works as intended for the most part, but the navigation directions that display in the IPC don't always work correctly and my off-road screen dissapeared. I scanned my truck and found code U3000:46-0A in...
