    • Check the shape of the area that the lifters sit in the rockers for distortion. I found they wear to their individual lifters over time which means if you install new lifters they may not rotate or sit in the rockers as they should. Especially if one has been damaged like it has here...?  Also check the top of that valve stem for damage???  It looks like it has a damaged edge..??  Might be just the oil shimmering to make it appear this way...??  I'd also be changing all 6 of these lifters just as a precaution. Did you take the engine out or do just the head removal? 
    • In all my experiences with Chinese turbos, they all spool significantly slower than the OEM turbo.   The max psi is dependent on your rpm and load. In my experiences, tightening the nut will allow the wastegate to stay shut longer allowing you to build boost faster, but then you run the risk of overboost. I'm not sure of the exact numbers, but overboost will set if you go over 18psi for 5secs. Once overboost is set, you will lose power and cannot rev past 3k - you can cycle the ignition to reset. Overboost doesn't always get a CEL.   Adjusting the wastegate on these Chinese turbos will not solve your slow spooling issue....the turbo lag will become more pronounce and you will constantly set overboost limp mode. On a flat road, it will allow you to be quicker, but then as soon as you hit a steep hill, or downshift to pass on the highway, you will go into limp mode when you need power the most.   My 2 cent.
