    2018 3.5L F150 411whp 4440wtq Anyone see come ways to improve?

    The attached tune file made 411whp and 440wtq on a 2018 F150 3.5L that other than 34in tires (295/60/20s) was stock. Both runs made on 91 Octane, and in same gear (I removed speed limiter from stock tune to get a good applicable baseline).

    I can not take 100% credit for this tune. It was modified from another tune file that someone had shared on the forum. It was done on the dyno and I have used the same tune in multiple vehicles. Overall impression of the tune is very good, but I personally feel there is some room for improvement. All the trucks that have this tune do some towing of boats/campers etc, so I like how the boost comes in not super aggressive for a towing performance tune.

    I am also attaching the original file so everyone can see the changes. Just looking to help everyone and myself improve these.

    Do you happen to have a log of the dyno pull for the tuned run? The torque spiking early, dipping, the rising some and leveling off looks like you’re running into a limiter early. Many tunes are designed to operate that way, but it can make the power delivery feel kind of like its surging.
