2020 F150 5.0 10R80 Tuning Help

[ECaseyP]

I have a coworker that has a 2020 F150 5.0 and he wants me to tune a few things for him. I'm not really experienced in tuning and I'm only trying to help him out.

There are no power adders or upgrades to the engine. He wants Start/ Stop turned off, adjust the speedo for 35" tires and smoother shifts for the transmission(10R80).

I haven't hooked up to the truck yet. Are there multiple computers to download? The reason I ask is because when I tuned my 14 Tahoe it had 3 and I only needed to down load 2.

Any help would be appreciated!

I have searched and haven't found anything on my question.

Yes it will require 4 credits to write both the PCM/TCM you don't have a choice. The adjustments are pretty easy, although smoothing shifts out, does he mean it's flaring and wants to firm them up, or it's too firm already? DM me and I can help you out some for the basics.

When I get a chance I'll message you. I still haven't downloaded the guys stock tune, but plan to one day this week. Thanks for the help!
