Default New injectors and now sputtering at or above 2500 rpm

Ok guys so my truck has been in the shop for awhile due to me not having the diagnostic tools to get it right. Well anyway today I got the truck back and now after I go past 2500 rpm it will sputter and then go back to normal and it doesn't matter what gear I'm in or how fast I'm going it will still do it after I go above 2500 rpms. I also noticed that my fuel gauge is moving up and down alot as well. Does anyone know if this is normal for a truck with new injectors or not? It has seem to be getting better since I have driven it today as well

May take some miles to get all of the air out of the system after an injector swap

Not to offend or anything but the shop said that they have gotten all the air out already

No but I did over the past couple of days. It doesn't sound like it ran out of fuel and got air in the system it's more of a hesitation that starts at 2500rpm.

As said the sputter could still be a trapped air bubble. Get on a back road some where and run the total hell out of it for a couple passes. That has helped several people get the air out if that is the issue. The fuel gauge bouncing up and down is a different issue all together. Fuel gauge has nothing to do with injectors, factory or aftermarket.

It's more of a hesitation than like its running out of fuel sputter, almost like theres too much fuel. It goes away past 3k rpm (I've been doing wot runs since I got it back and discovered that issue) but I'm more wondering if this is a normal issue for injector replacement or if its something else.

I did have an issue before it wouldn't start and I found a loose wire on starter solenoid but it wasn't rpm related it just happened. This issue is rpm related because any rpm below 2500 and it runs perfect just a little rich.
