Throttle body upgrade 2v 5.4
Got an 03 f250 with the 5.4... I'm trying to get some power out It but staying naturally aspirated. It's got over 200k miles so I'm not gonna go crazy lol. Previous owner put a CAI on it and I'm gonna redo a true dual exhaust. I'm thinking 75mm bbk throttle body, tune from 5 star, anything else yall would reccomend? Considering a regear but not sure how much that would run me....

Short of a power adder there ain't much you can do. There isn't much gain in a larger throttle body or a cold air induction kit. The stock 2V 5.4L just doesn't breath enough to make use of the extra capacity..
A free flowing Y Pipe or even true dual exhaust will give you a little more push on the posterior dyno, but don't expect miracles.
Regearing to a higher (numeric) differential ratio is probably the most cost effective way to increase your power to the ground, maybe a 4.30 instead of a 3.73.
