Hate you are having these issues but they are a great teaching tool for the rest of us out here watching your pain. Cant wait to find out what this latest problem is, thank you for your content.

Its amazing how these tuner guys seem to know more than the factory
Take a look at the different ford performance catalogs I believe its the 2018 version that talks about ecm tuning and how tuners are actually doing more harm than good
Like Ive said before
A well tuned stock vehicle will out perform a poorly tuned modified vehicle every time
Good luck in the hp quest

It’s the clutch... the metal from the plate sticks to the sensor and messes up reluctor wheel... am sure it’s a McCleod clutch.... you will have to get a single disc organic clutch... recommend the Speck 3+

What fuel, or fuel additive are you using? Your plug looks like mine looked years ago when using a certain hi octane fuel.(the brand escapes me)

If this is a problem it will show up on a data log.
