i got 176kw on a forged gen 2 with a hiflow ct26, PFC, cooler, intake and exhaust with an ebay dump pipe with a supposedly hiflow cat on it running 14psi
my intercooler fan wasnt working and intake temps skyrocketed ( i think it was around 60plus degrees)
the intake temp. has a lot to do with how much power you make.
and a puny sidemount with no aftermarket fan on it (or in my case fan not working) aint gonna cut the cheese.
170ish kw is the norm for a gen 2 running a ct26 on 14-15psi going by the yank forums.
i think you need to fix the shutting off problem first then move to the next problem and solve it.
