New Ford F350 w/7.3 gas ?
 

Just purchased a 2020 F350 C/C 4x4 XL LB with the STX and FX4 pkg. I got the 7.3 gas engine with 3.73 gears. Anyone know of any tuners on the market yet?

Good luck with your new toy !

If I might make a suggestion, before laying out some $$$ for a tuning appliance, do some research on how those appliances affect the electronics in today's vehicles.
Everything from trouble up the road to no starts appears on the list.
Just because they sell them and HYPE them, is no guarantee they will not cause problems with the electronics in today's vehicles.. Some systems in today's vehicles are so sensitive that temporary add on's affect vehicle electronics. FORD vehicles in particular do not like add on's. There are many instances where vehicles went in for performance problems only to have the remedy of removing the add on gizmo. For what it is worth , you might consider checking with a few Ford Service Departments.

The systems in today's vehicles can be affected by something like a slightly corroded connection , that can be a stinker to find. And when an add on contributes to this problem with uncontrolled frequency variations the problem can be extremely difficult to pin down. Certainly worth your time checking this out.
