p pump 24 valve injector question

Ok so I'm running the p pump and am extremely happy with it. The injectors I have are still the 24 valve pop off pressure. They are 8 by 11's. I was thinking about going with a bigger set of injectors like a dynomite comp or f1's or something. Who makes a good strong injector and should I have the pop off pressure set for 12 valve or 24 valve since I have the p pump. Thanks for any input.

My truck:
1999 Dodge 24 Valve Cummins
P pump conversion with a 180 pump
Pump doesn't have a fuel plate, 4g springs, & full cut dv's, no afc, ect..
.093 fuel lines
Air Dog 165
custom ground cam
mahle pistons with .050 valve reliefs
balanced rotating assembly
8 x 11 injectors
ported head with 60lbs valve springs and 12mm studs
Pro 52
Polydyn header
stage 5 east coast diesel bullit automatic trans.
triple disk dunrite torque converter
4.10 gears
klienn train horns
Nubers with the twins and without header
603hp 1157tq
12.7 quarter mile (then ht3b blew again)

Give both DDP and F1 a call. They will help to get you set up exactly how you want it. I would run with 12v pop pressures, but I hear that there is more too it than just that.

i talked to a guy at dynomite who clearly didnt know what he was talking about. i asked for his recommendation and he said a set of 110hp would be plenty. gregs running a set of 110's with a smarty and a stock turbo. i think 110's would be extremely weak for my set up. going off my specs in my sig what would you guys say would be a good sized injector. id like to stay around the 600 to 650 mark. i am going to run either a 250 or 275 pressure.

I would go with a set of 250's or close to that. I would have them set for ppump pressure. I have seen a few sets of ddp comps for sale. My local shop has done a few ppump conversions I am sure the would be happy to talk to you about what you want and drop ship you the right set of injectors for your setup.
