I have a 2013 F150 FX4 5.0L V8 4X4 3.55 gears with the Roush 2.3L supercharger and Roush cat back exhaust. It's got a 2.5" leveling kit with 33" tires and 18" wheels. The truck is pretty quick, and I really like that because I'm a big horsepower guy so I'm taking my truck to the Gimli Racetrack on Friday to see what it does. But, all of my life I've wanted a lifted truck. So I've been seriously debating on buying a 4" suspension lift, but I think it would look better if I had 35s on it. I don't want to lose my speed from heavier bigger tires! Is the difference negligible? Or if I change my gear ratios would that bring me back to the same sort of speed that I was before? My truck also came pre-tuned and when I bought it it didn't come with a tuner. Any help would be appreciated!

I've just joined this forum (I'm a long-time member of another), so I'm not sure of the best section for your quesiton, but you might want to start here: https://www.f150forum.com/f97/

And please title your post with more than "Need advice!!!" Something like "Need advice of tire size on supercharged 4x4" will get you better views and results.
