Some tunes are legal. Some are not. By this thought, changing the final ratio would also be illegal because it alters the truck's OEM configuration that it was certified with. Almost all of the perceived improvements from tunes are from simply increasing the gain from the TPS. The little bit of actual hp gain is at max rpm WOT where we seldom if ever drive. I happen to like the lethargic feel of the loud pedal in my stock F250. I know it's there if I want to floor it but it encourages lighter throttle as it is. I like to try to go easy on the truck.
Ever since the drive by wire systems came out I hate the throttle delay. The very first one I drove had the lagging throttle response. I didn't know it was drive by wire till I opened the hood. I like my throttle opening 1-1 with my throttle pedal. So I know I'm getting 100% performance. The manuf like to hold back throttle opening. Like my 13 Explorer with the NA 3.5. Under WOT from a dead stop you only get about 65-70% throttle opening and then it slowly ramps up to 95% at 20mph. It's a dog, over 25mph it moves. As soon as the power train warranty is up I'll be getting a tuner from 5star for it.
