Cm871 reduced power

[Scoot5869]

2010 cm871 500hp set to 550
So recently, I’ve been experiencing a low power issue. The truck won’t really boost past 30 psi It takes forever to get up to say 65 miles an hour on the interstate. Sometimes it tries to tries to run “normal” as in it will surge up for a second.
I’ve monitored stuff on insight and don’t see anything out of the normal. There’s no smoke at all the injectors checked out good the cut out test checked out good

I just replaced turbo because I assumed that the turbo was going out unsure of how old it was and knew it had bad programming ran through it for however long. it came pre-programmed still did not fix the issue changed the intake sensor that didn’t help anything either.

I replaced the whole fuel system this spring minus the gear pump had a leaky fueling actuator that I replaced when I did turbo

It doesn’t throw any codes and the turbo readings are both the same. It just seems like the truck is derated and there’s just not the power it had going to the gears. It feels like I’m driving a 300 hp truck versus a 550 hp
truck has been demandated Programming was all taken care of on here. Checked the cac and it was good replaced all the boots as well new fuel filters and air filter

I have not done the bubble test on the injectors yet it doesn’t seem like an injector and it ran on every cylinder by themselves just fine.

pretty much at a loss of what to do or what to monitor right now help would be appreciated. Thanks.
