yeah you will need forged to go with a 150shot, and you will need the additional fuel as well.
theres a guy that used to be freinds with my dsm buddy who ran 125shot for 3 years on his GT with nothing more than a tune and some boltons. one day for ****s and giggles he went to the 150 and leaned out and cracked 2 rods clean in half. he now has a modular 5.1 forged with VT heads/cams and is making 400hp without the nitrous
, and 560 with the 150shot.
hes using the 1300$ wet nitrous kit(i think NOS makes it for the 4.6).
