Seriously, the big item on this list of unknowns is the turbos. You need to know exactly what was done to them. I would be shocked if it didn't have a 3 bar in it. The fact it didn't make good power with meth makes me wonder what was done to the turbos. And without the meth higher flowing turbos are pretty much useless from what I understand. The stock fuel system alone cannot support anything higher that the stock turbos maxed out.
Hence why my head hurts, I can imagine yours does too lol.
