  • Without serious physical modifications to the truck (beyond quickie mods), the optimal tow tune for heavy loads is about 40 HP - while keeping an eye on EGTs.
  • The stock injectors and stock tuning leave about 60-65 HP on the table to tap into with performance tuning. In translation, that means Ford didn't put an injector in there that's capable of 140 HP more than stock tuning - that's bad engineering. If you want to realistically boost performance (without expecting improvements in MPG), stick with the 60-65 HP tunes.
  • I know those 80, 100, and 140 HP tunes give the impression of way more power, but the proof is in the stopwatch - not your ***.
Good advice. I rescanned for codes and got a P1249. Iím wondering if my wastegate is sticking in causing some fuel mileage issues. I do have the red hose connected To the wastegate actuator.

Most of us remove the red line from the actuator and just plug the vacuum boot on a nearby CAC boot bolt. Watch for overboost code.

Update

I sent my injectors in to Fullforce diesel and have them flowed. The results are all flowed as expected for stock ADís except for 1. One of the injectors has a clogged nozzle, which they replaced for me. They said two of the holes were clogged in it, which would show were my symptoms of trailing black smoke and poor fuel mileage are coming from.

Ive already done the glow plugs and UVCH. Anything else I should have my mechanic do before we get the injectors back from Fullforce?

Pressure test cooling system to check cups for leaks?

This may be a stupid question, but can the system be pressure tested with the injectors removed?

That's the only way I test the cups for leaks - injectors removed. I drain the coolant and pressurize the cooling system with air to no more than the rated pressure (about 14 PSI Max). I spray silicone lube in the open cups, and watch for bubbles.
