Injectors? How big should I go.

Hello,
So I am looking for some information on Injectors. I am just starting to have some stiction issues at highway speed under light load. I am thinking about just using 1500 grit sandpaper on the spools and going through them with new o-rings, but I wanted some more specific information first. I would like to get a little more power out of my truck in the future, and was wondering what size, or how many cc's I might need to make lets say 500hp. I don't know if that is a reasonable goal for me, I'm just looking for some advice from persons more experienced than me about what I can do. I want to keep my truck reliable, but more power is always nice. My truck is at stock power levels, with a IPR egr delete, a bypass coolant filter, an Airaid intake that was on it when I bought it, and a 4" cat delete, side dump exhaust. The truck isn't tuned to my knowledge, but the egr delete doesn't set off a flow code.

what sounds like a feasible power and torque goal for a reliable truck? also How big of an injector can I use without studs, at stock power?

any info or thread references would be much appreciated.

All fuel no adders:

stock injectors
stage 1, stage 2, Hybrid turbos :vgt turbo

500-580 rwhp:
same as above but 155/30, 175/75,190/75 injectors
fuel regulated return and fuel upgrade for 175-190 injectors
upgrade tranny at 570-up

590-690 rwhp:
stage 3, stage 4 :vgt turbo
190/100,190/150,200/150,205/100

Re: Injectors? How big should I go.

I would not go bigger then 155's on no studs but then again I wouldn't try to push 500hp without studs, it's a must for a reliable build

Re: Injectors? How big should I go.

2Dstorm thanks for the numbers! And yes I don't plan on making that power un-studded. Just don't have the coin right now. I forgot to mention the truck has 158,000 miles on it and I did do the blue spring mod and have 6.4 banjo bolts to put in it. and am wanting to do a powermax turbo, or a hybrid down the road. I do plan on covering the basics before I add power.

If those numbers are the case then all I need is stock injectors for now, and I can have the nozzles and plungers modified later right? I want to do so much right now but my wallet only lets me pick at the mods. what is stock injector cc's anyway?

If you have time to let the truck sit you can send the sticks to warren 175/75 will run you 1250 that is 70rwhp you will have to tune the truck

Re: Injectors? How big should I go.

For 1650 warren will build 175/75's with the new spool that will eliminate the injection stiction issue several guys are running them and they are getting awesome reviews I think they are worth the extra $400 bucks it's all in what your budget will cover. If you are not running a tuner you will have go get one with bigger injectors I prefer the sct tuner I have the itsx4015 it is awesome the canned tunes will boost your power but I suggest custom tune if you really want to get true power out of your truck. I like innovative diesels tunes, I also like tsd's super panty dropper tune (currently running) it's very powerful and responsive try a tuner before you get injectors you will see what you have been missing
