The truck was running good with the stock injectors till i change them for the
DEKA IV ( DEKA 4 ) Mototron 60lb/hour High Impedance Injectors.

At idle the truck shakes and air fuel goes tup to the 15.8, driving around it drops around 14.3 truck drives good, and i when i get to stop air fuel goes back to the 15's.

CAn it be getting air somewhere since i took off the intake to change the injectors outside.

Have anyone got htis problem??

The only thing i can think about is the intake its getting air or the data is not correct.

make sure everything is seated well, all o-rings are on properly, etc. Did you replace intake gaskets since you took intake off?

You don't need to replace intake gaskets unless there's something wrong with them.

Are you sure that the injectors are scaled correctly? Did you make any changes to the pulse width?

Yes i change the 4 tables.

offset vs press vs IGNV
flow rate vs prss
short pulse adder

What do your fuel trims look like? I put those same injectors in my truck and used all the data from the Banish dvd and had to touch up the ve and maf...I would never swap injectors and just assume the tune is still fine and there's something else wrong, you might end up chasing your tail

Where did you get your data from? If it isn't from your exact injectors they won't run right.
