Good gear ratio for supercharged 2016 F150?
I got a 2016 f150, 5.0 liter and had the dealer install a 2.9 whipple. So far I'm not too impressed. I think maybe because I have 3.31 gears. I am wondering what gear ratio would be best to switch to and if I will see much difference. Also I should mention I put 275/65/20 BFG ko2 tires on so that makes the tires around 34" diameter. Any suggestions?

3.73 minimum. I have that with 32" tires and it kicks *** with my Roush setup. Most guys will suggest a lower gear/ higher numerically. The lower gear you go, keep in mind, you will be quicker off the line, but higher RPM's on the highway. Guys will run all the way up to 4.56, I'd suggest somewhere in the middle, low 4.?

I personally went with 4.56... i have a roush supercharger with 72mm pulley, 56lb injectors, fuel booster, 67mm twin throttlebody. Right now i have an email tune which im not entirely satisfied with... im getting it dyno tuned next week. I got 35" tires on 20's. I went with 4.56 because i wanted better mileage around town as i dont plan on using it for long trips and also for the occasional 1/4 mile run..
