Nice looking truck! I like your body style more than my '99 F-150 but mine is paid for, now with 85K on the clock, I'm kinda stuck with it.
I use to play with a lot of hot rods making mods engines and carbs, exhaust, etc. but today, I'm not going to mess with trying to re-engineer modern engines!
I remember doing some slight mod, like ram air thinking in my mind I had improved performance, not really, that was more in my mind because that's what I expected.
IMO, everything works in concert as it is designed, change one thing you effect something else. If I ram more air in, the fuel mixture needs tweeking, then the exhaust has to go out, then the timing, then electronics and running hard may just get me a blown engine.
If I need all the mods then I'd go through the entire engine design building everything to be more efficient as well as powerful and the trade off would likely be reliability.
Just saying, I wouldn't do some engine mod just because someone else did it or based on their perception, I'm going to trust the engineers and shoot for reliability more than 5 more HP or what sounds cool.
Now, the GPS mod, nice! I picked up an Alpine 928HD, I have to do some cutting and molding to make it fit, but I'll also buy a stock dash panel to replace my interior mod in the event I do sell it someday, another buyer may or may not want what I do to my truck. Another reason I leave out shade tree mods under the hood, resale.
Nice truck, best of luck and adventure with it.
