Fire Rescue124

Ok i am sending my stock injectors off to get worked. Now what should i get. i am looking to hit 600-650hp everything on my sig is on the truck, and i will be getting a cam in the next month or two so keep that in mind as well. i was thinking about 120's but was told that 90's would do what i am looking to do. i also only want to do a bag of parts on the CP-3 so i also need to keep from draining the rail.

Thanks,
Eric
