Dyno day....

Ok so I dynoed my baby not too long ago and was wondering about a few things. Such as maybe advice for pulling just a bit more hp outta my baby. I don't wanna risk breaking it but just maybe 5-10 hp more would be nice.
It is an 03' 7.3 CC LB Lariat (with roughly 95k miles on the day of dyno)
The mods on it are:
1. MBRP 4" turbo back (flipped muffler so the scoops face back)
2. AFE stage 2 intake with a proguard 7 filter
3. 16 pos push button shift on the fly switch with assorted tunes from DPtuner (Max tune is 140hp extreme.)
4. AFE Bladerunner Intake (it actually gave me 2.5 psi of boost over factory 27.5-30 peak)
5. Autometer guages. (boost, pyro, and trans)
6. 6.0 trans cooler upgrade.

But any ways I ran it and it peaked at barely under 300hp. I have the run sheet but not with me. I'm currently deployed but can have my girlfriend send me a pic of it if needed. Not overly upset just figured it would've been more, several guys told me that their trucks were running low on the dyno that day and maybe the dyno was running limp. They said that they would guess the truck would be over 300 hp that day. I guess the only way to make sure would be to run it a few more times and average it.

One thing sticks in my mind though when they ran it the last time I told them to push to 13.5 pyro and the truck seemed to surge. they said it was the rev limiter. I wasn't aware that they even had rev limiters... Is that what happened or is it something else? Any ideas or suggestions would be awesome.

P.S. future mod when I get home will probably be a water-meth injection by snow performance, very likely the MPG-max system.

5-10 more hp?? Guess the big hp bug never bit you.. 1000 on a water meth system is kinda a little overkill for the mods you have listed though, maybe others will chime in but I don't plan on running a kit like that till I get bigger injectors.

true a grand is excessive but if the mpg claims are what is hyped up then with time 1-3 mpg increase is well worth it. I know it will take years for it to pay for itself but hey when I tow I don't have to worry either... and larger injectors mean slightly less mpg... don't know god I hate decisions..... Mileage or Horsepower????? FML

single shot injectors over split shots mean better mpg as long as you keep your foot outta it.

are you running the blade runner intake manifold? What are you running for an air filter?

Yep blade runner manifold. As mentioned before its a pro guard 7 filter. I know it's thicker than the rest but more filter=safer to an extent. Wouldn't consider a k&n for a second. Too many reports of people dusting their turbo wheels.

If all your really after is 5-10Hp, you could do the zoodad mod (would help till you get the hood), or go this route 7.3 Power Stroke IDM Modification supposed to add 15-30 but I have read it mostly gives a more notible acceleration

you could also get the FRx from riff raff, maybe if you have the money step up and get a complete regulated return fuel system. That will help out quite abit with fuel economy as well.
