2005 6.0 need some help!

[B.M.F Racing.]

i just recently bought a 2003 6.0 with a dropped lifter and a wiped out cam. cant complain i got it for 1000$. i bought a 2005 6.0 engine from a local salvage yard with 133k. i fully rebuilt engine. studded,egr delete, regulated return kit. i got the motor in the truck now and everything runs great!!

i installed and airdog 165 s&b intake and a 5 inch exaust. also loaded an sct x3 to it. truck runs great and is pretty fast.

my main question is whats next for more power.

i already talked to vivian @quicktricks. shes sending me some custom tunes.
looney wild and looney wild track for nitrous.
i have a brand new stacker 2 from nx ready to install.

how do these transmissions hold up? the truck has 4:10s and seems to shift great.

could i run a set of 155's with custom tune and spray and be safe?

thanks for any help. im new to 6.0s
