Power problems

i just recently had the front structure, new head, new air to air, done on my 6NZ cat. After the mechanic put it all back together and we fired it it seemed to be running ok. But I thought that it had a miss to it. Come to find out check engine light came on.... the cam was off one tooth. It got set right and timed the engine again. Replaced the crank shaft positioning sensor and went back thru the overhead. Engine sounded and ran much much better. Now the problem is.... anytime that I'm getting ready to go into a hard pull, there is no power and I have to shift down several times just to keep the truck wanting to climb. I can hear my turbo spolling up but almost like it's not spolling all the way. It's almost like driving a diesel motor with no turbo at all.

Does anyone have any suggestions of what it can be? Keep in mind that the motor ran great before we did all of that. Just needed to fix a lot of oil leaks and head ended up not being good.

 

I do have a boost gauge... come to find out it doesn't work. I'm replacing it tomorrow. And forgive me.... what would the CAC be? Also I did plan on going thru all the clamps and hoses tomorrow. I don't believe that it's anything internal. No check engine light. Also... my turbo was replaced a year and a half ago. So I didn't think that was the problem either.

Now here another thing... the gasket on my air compressor is going out. So it's got a pretty good tick sound to it. Could that also add to my problem? I'm also going to replace that tomorrow.

 

Ah ok. My CAC is brand new. Had to replace it too. My old one was cracked and wouldn't hold pressure. So I sure hope that isn't the problem. But I will check it out too.
