Engine missing with new injectors

I just installed My injectors (stage 2 DIY kit from DPP) into my 02 PSD. The truck starts great and revs in place great. driving down the road acceleration seems better but from 35 - 55 mph i get a shutter in the truck. It feels like the torque converter is slipping but thats not it. I checked for codes and there is nothing. I also replaced the vavle cover wiring harness, valve cover gaskets, and glow plugs. If i stomp on the gas it doesnt shutter, if i let off the gas it stops shuttering. it will only shutter when i am just cruising. when i first went for a spin it was really bad. as i have put more miles (20 miles) and run time on the motor (1.5 hours) it is getting better. I have heard from several people that this sometimes happens when injectors are "fresh rebuilts" but i have never come across this, so i dont know if they are BSing me or not. the truck has a cold air intake (just cleaned), a 4" exhaust turbo back. I have a programer on the way with custom tunes but its not installed or here yet. any info would be great.

Thanks
Will

It can take up to 50 miles to get the air worked out of the oil and fuel rails. If it seems to be getting better, I'll bet that that is the problem.

Just keep driving it and it should clean itself up.

I would give it a good 50-60 miles and several start ups to get back to the norm

Looking for 05-07 front end with Harley Lights

I have about 40 miles on it now with about 6 hours run time. Cylinders 1 and 3 are dead. when i go and start it up and let it idle and touch the exhaust manifolds 1 and 3 are cold and the rest i cant even touch. it keeps getting better so i am gonna keep on driving it until i hit about 75 miles then im gonna do my trouble shooting. any recomendations on where to start rather than pulling the injectors agian (buzz test?)

If 1 and 3 are totally dead and cold I would bet that the harnesses for them came undone
