2010 f450

[Captain Morgan]

Doing some work on a truck for an older gentle man I know. Getting the dpf delete and I think the mini Maxx tuner thanks to performance truck. But I wanted to know if there is any way to program away the speed governor? Or is it a head part in the trans that would have to be redone? This guy can only go 78. He has 4.88 gears. Did he shoot himself in the foot or is there a way around it? Oh yeah forgot he can't set the cruise higher than like 72. it almost got him in trouble in Texas he jumped into the high speed lane trying to run 85 and almost got Run over when it pegged out at 78. Thanks guys.

you can adjust the speed limiter to what ever you want when you load the program, its part of the set up, i think after it asks if you want to adjust tire size...re load the program and you will see it , you must have skipped over it the first time....

You can raise the limiter with the H&S, but just keep in mind that the 19.5" tires on the 450 are technically not rated for those speeds.

I highly suggest re-gearing. It will be expensive, but well worth it. The tuner will help, but ultimately the best solution is to re-gear it.

+1 for the tire rating issue

+1 for re-grearing

Commercial tires are rated for weight and speed just like Car tires, while you can run 85 MPH the tire could suffer a catastrophic failure. Check with the tire manufacture ( Company not dealer) to check on the speed rating.

I went with 265/70R 19.5s 34.5 tall effective gearing is 3.98:1. 60 mph =~1850RPM

Has anyone used a Gear Venders overdrive i was thinking about it on my 450

I visited The factory in San Diego two year ago and this is what the engineers told me.

The unit will work with a diesel 350/450/550 but it is advised that you only use it in the OD mode unloaded. Putting a moderate or heavy load on the truck and engaging the GV O/D will result in shortened life and premature failure. The System was not designed for the harmonics and torque load that todays Pickup turck diesel produce.

The system is designed around a Volvo Penta cone clutch and yes they do install these things in a variety of hot rod cars, the difference is the harmonics and high torque loads that diesels produce. Diesels eat the cone clutch.
Gear Vendors does not trecommend trailer towning with the unit enganged.

Gear vendor does not recommend carrying heavy loads in the bed ( Slide-in Camper) with the unit engaged. They do say it will work just fine in a pickup as long you are in a unloaded condition.

Also their approach is a one size fits all, so the same OD unit that goes on a 32 roadster at 3200# will the unit they use on a F450 at 9900# empty. I was headed down this road until I visited the factory, at that time they told me they had no plans to update the unit or build a unit with better capacity.

This said I know there are folks out there that use the GV O/D, the one guy I know personnally used in a F350 2wd to tow a 12,000# fifth wheel it broke down after the third tow.


Hope this helps.

PS I have a GV OD in my 34 ford PU, but it is a toy and not used for work.
