I have the 3.42 gears and overall pretty satisfied. Usually check MPG's on runs up to our camp approx 75 miles from home. 8 miles at average of 40 mph, then 57 miles on the interstate with cruise set at 70, then another 7 miles on back roads around 45-50. If I'm running with nothing loaded it gets 15 mpg, 20.5, and back to 15 again. About 17-18 average for the trip. If running loaded: groceries, utility trailer with a John Deere lawn tractor, weed eater, gas, and any tools I might need (2200 lbs towed), and 2 adults it drops 1-1.5 mpg to 16-16.5 for the trip. Quite happy with this. It's 3 mpg better than the F-150 with the 5.4L and 3.55 gears I traded in. Not sure if there would be any benefit going to the 3.23 in my case IMHO.
Speed limiters have been around for over 20 yrs. It's not just trucks that have them. It should be expected. If you want it removed, get a tuner and turn it off. Check out the tires on the police vehicles you mentioned. I think you'll find they are rated for higher speeds and the ones on your truck aren't.
Donstar, I think overall the only option to gain some power is to boost it. With the high compression and fuel systems in these Gen V engines you wouldn't be able to use a lot of boost like the Fords do. It would probably be impractical financially and shorten the reliability. I have not done this to any of these engines, but I did put a centrifugal super charger on a mid 90's 350. Made good power but the upkeep was a pain. Just my opinion, but your thread looking at the 2018's with the NHT package is probably the best way to go. One old guy to another.
There is a third issue with turbo and super charging. Fuel usage. More fuel is needed to make more power. Air doesn't burn by itself. The Ford 3.5 ecoboost is a prime example. Under load, with the turbos spun up, they get terrible mileage.
I'll give another positive response to this fix. Didn't experience the lag in response all the time, but occasionally it would be slow to speed up on turns at intersections and such. Biggest thing that bugged me was when you want to override the cruise control and it needed a big push to gain any speed. When I first checked it didn't appear to be flexing. When I pulled up on the pedal it moved quite a bit and after doing that, pushing down lightly the flex would be there. Didn't have a paint stick laying around so I taped a couple of 1 in diameter washers together to use as a shim. Worked like a charm. Throttle responds instantly now.
DONWT15 replied to 3737's topic in 2019 Chevy Silverado & GMC SierraThe reduced gear offerings are probably a cost cutting move. Fewer choices means less parts to maintain in inventory. Less inventory = less cost, storage space, and less taxes. Manufacturing companies (all companies actually) pay taxes on their sale-able inventory. If it sits on the shelf it costs money. Based on the numbers being bounced around with the transmission gear ratios, you should be able to get comparable performance. However the loss of a choice is annoying.
If memory serves here, the key in the column with the obnoxious rotating cylinder to lock the column was intended as an anti-theft device in the late 60's. As far as a button to shut the ignition off, what's the point? If you still need the key and the button doesn't start it also, why bother? Maybe I'm missing something here? I'll have to check with my grand daughter again to straighten me out.
