Does your truck smoke like crazy?
Does it lope?
Get a fuel pressure gauge because with that big of injectors, maybe they dont have enough pressure for the volume? (time for 13mm pump ;-) )
By 165lbs valve springs, do you maybe mean Hamilton's which are rated as so?:

Sounds like you could have an 800rwhp truck really fast if you figure out your issue. Does it smoke like crazy? and at what RPM does the turbo light? Are you sure you are spooling the turbo on the dyno? I have heard of people not being able to spool it on the dyno for whatever reason and then getting a spool valve, or smaller turbo and making more power.
Or... are you just a troll?
