Some issues after upgrading turbo
I went with a powermax stage 1 and had the dealership near me install it. They have installed several aftermarket parts for me when I am being too lazy or I don't want to mess it up.
After picking it up I am now seeing a lack of power, slower throttle response, higher EGTs, and there is a slight burning oil smell.
Any ideas what could be the cause?

Most folks who put in a Powermax turbo have the same issues. I put one in and put up with it for a number of months. The truck couldn't get out of it's own way. Finally I bit the bullet and got a tune for it. Most everyone had told me I was going to need a tune, they were correct. All was good after that.
You are going to need a tune.
Mine smelled at first also, just burning off any of the coating from manufacturing. It went away.

Boost levels are not as high as they were before, but not too far off. I was pushing almost 35lbs, but most were telling me that was not normal and my turbo was about to go out. I am now seeing 29lbs.

My powermax did have lower boost than stock and acted like u describe, it does need a tune to really make it shine. your peak boost sounds right, 35lbs your old one was ready to lift your heads

UPDATE:
I did the VGT relearn process twice since I am sure I messed something up the first time. The truck is running much better now. The shop did find a slight oil leak from one of the gaskets on the turbo and they are fixing that tomorrow. Hopefully that will salve all of my issues.

I didn't notice where you lived until just now. We are in Gettysburg. Came for the weekend. Pulling out tomorrow.

So this is an 03?? I've had massive issues with the 03 Pm. Finally I took one of them apart and was shocked at how the unison ring grooves for the veins are not a smooth transition like later models pm's. It kinda makes a "v" in the grooves. I think it sticks halfway. Needless to say,, I don't offer 03 pm's nor will I install them. Just my $.02.

All right, so we made it to Dallas from Baltimore towing our TT that came in at about 13k lbs. I am not really happy with the turbo at all. It seems like my boost is still extremely low, not making more than 18lbs even with it floored going up a hill.
Egts are also running higher. I used to see about 1000 when towing, now i am 1200-1400. Fuel mileage has dropped as well.
So I am still seeing less power, less boost, higher egts, less fuel mileage. Using new tunes from Gearheads that I purchased after the turbo. Anyone have an idea on where I should start looking for the problem?
