Stock injectors will be fine unless you have some extra money and wanna upgrade them. Thats the same kit I have an egt's are never a problem.

I would try to upgrade the injectors while you're in there if funds allow, you'll need a lift pump and gauges as you mentioned.

Scott at SDP makes a really nice Compound kit.

Never seen more than 1150 here with my twins.

Stock injectors are just fine for an S475/stock kit to get you 550HP.

Let me know if you have any questions!
