I got a II stage 2 cp3 for a very good deal today that I could not say no. Its used but with low miles and I know the truck it came off of. I want to know if it will keep up with my DDP 90's and the TNT. Also should I keep my II dual feed line hook up too.

It will keep up once you get the RPMS up a little bit.. If I floor mine off the line with Flux 2's it will suck the rail pressure down to 8-9k and then go back up. It smokes like crazy when the rail pressure drops though. I'm running 1/2" lines from the Raptor RP-150 at 45psi straight to the CP3. Filters just changed.

Inlet pressure drops to around 40psi when I do this, and the pressure is taken at a fitting on top of the CP3.

That is with the TNT on TM 3, Level 3, Timing 2, Rail Pressure 1.

With that setup it makes 521hp on level 3.. Moving to level 5 and it seems to not really lose rail pressure but didn't make more power. This was taken on a Mustang Dyno (MD600) and not sure what it would do on a DJ. Also those were taken in 3rd gear (auto)

Oops just paid attention and noticed you got an II stage 2.. Not sure how that stacks up to my Floor It stg 2.

Form what I hear it probably depends on who built it and on which day of the week. Some guys have had good luck with the II units and others have had a simple arson kit do a better job than a stage 2. Hope you got a good one.

the floor it stage 2 will keep up with injectors twice that size and the smarty so yours should also I dont see why it wouldnt but maybe im wrong. I dont think you will have an issue
