How much does 3" inch lift with 35's affect PowerBoost's performance and MPG?

If you want the stock 20s, they sell new take offs all day around these parts for under $1k. There's a couple dealers around here that sell the trucks as packages with lifts / wheels / etc.. thus brand new stock wheels / tires are cheap

F means I can inflate them at a higher psi. Is that good. I like the factory wheels it has. You guys think 33’s would be better? I’m sorry for all the questions. This is new territory for me. I’ve always had trucks. Just never a truck of this caliber

Stock is 33s without calling them 33s. Check craigslist for takeoffs like pictured. You should be able to find them complete w/ TPMS and swap out your stock 18s and not even have to re-program the TPMS. I'd bet Texas dealers do the same and you can find these 20s for sub $1k. Ford charges $1500 for these as an option. 275 60 20 is stock size for reference.

As for your tire, its specs will be on it both weight and max pressure. Stock pressure is ~35 psi. The benefit of running 20s over 18s is you get less sidewall flex both cornering and trailering. LT tires have much stiffer sidewalls, but obviously increasing wheel size reduces the amount of sidewall you're dealing with. 22" wheels w/ 34" tires is a sweet spot for trucks, but the stock 20s below with some 34" AT tires is a good looking / common setup many on here run with.

Any suggestions on how to adjust my speedometer to the lift and tires. I have a 5 mph difference

Here's the problem with 33" stock / leveled however -- 34" gives a bit more tire. Will try and find a few more w/ 33" and an aggressive tread. Light 34s won't affect it nearly as much as heavy 35s. The larger the tire and the higher the lift, the harder the mileage gets hit. It's all about tradeoffs.

You need an adapter for forscan. Worth every penny just for the modifications you can do to the truck. I've got about 12 different settings enabled like remote window up/down, fog light settings, none of the double honk running truck nonsense, no seatbelt minders, etc...

This is the forscan thread -- lots of options

Your truck sits nicely as well. Yeah I do like the aggressive stance. So far only driving the sped limit. I’m getting around 19.2 from work and back

For reference, I'm on stock tires w/ the 2.25" front level and my interstate mileage on a recent 600 mile trip was 19.6 of which most was at 80mph, though it was up to 95mph in some stretches. I have no qualms in 'chasing' traffic so long as there's a blocker ahead of me to take the hit

 

[fgutz3rd]

Yeah true that. It’s like I feel the power and want to just open it up just a little you know

Powerboost is heavy truck -- with you in it it's easy over 6klbs. That's extra mass to offset trailer weight. Strongest frame of all F150s sans raptor. GVWR is under-rated for what it's got. A lot of F150 trims are around the 5klb mark. All of the additional weight is inside of the frame rails so it's got a good CG for what it is.

I understand but it is drinking gas faster than a drunk man can consume alcohol. I didn’t think it would affect the miles per gallon that bad. I’m getting may be 13 to 15 miles per gallon. Does that sound right for a power boost? It’s lifted with 35.? I’m almost to the point to where I want to remove the lift and get rid of the tires which are brand new and drop it back to stock.

19.6 is a lot better than 13.5 or at best 15. I want to pay someone to remove the lift so I don’t have to put fuel every few days it seems.

I'm running 34s and the speedo is off less than 1mph per GPS and road displays. Not sure how you're 5mph off.

I downloaded a speedometer and even online I set my cruse to 70 and every app and fee online speed checker apps have me going 5 over every time
