heres an update.

i brought it to danny aka greengoblin. and he did a leak down test. we found something very supportive to my origional theory. bank 1 was perfect showing normal leak measures however bank 2 showed something a bit differant. all the cylinders at TDC were leaking slightly-when pushed a bit passed the mark for TDC for each cylinder, the leak will stop indicating that bank 2 is off timing. possible causes.
the machine shop decked my head to much? the small timing chain on bank 2 is off a tooth, the valve lash can be off on that bank only. this explains why the bank is lean even when the injectors are pushed to 80 % duty cycle on that bank. when boost kicks and the heads become pressurized, the pressure sends all the fuel past the exhaust valves before it can be ignited....

Jwt does have a template Under manuals so you can easily check if the timing is right.

I pulled the car apart and the timing was spot on. I think its a decking issue, I have the head off and the valve lash clearance is very low .241-.279 on intake side and exhaust.
.279-.305 Everything is in the low side and bellow desired spec. Some were in spec but barely. Now I know that decking wouldn't mess with valve clearance but it's defiantly off. I'm replacing both heads and hopefully it will be back in order.
