You're welcome for the manuals.
One really important thing you should know, that is do not turn the spill control valve screw in more than 3/4 turn. At 1 full turn, your engine will go into run-away. Yes, I have confirmed this does actually happen. For me it did not happen until I revved the engine up. When I let the throttle off the motor kept going right up to redline. I had to crawl under my hood and turn that screw back out with the motor screaming right by my head. NO FUN!!!
Turn the screw 1/8th turn at a time. In for more fuel, out for less. Take a picture before you turn it at all so you have a reference to the original position. Oh, and there should be a little steel cap on top. Just gently pry it off first.
You will need to add more air with the additional fuel. I forget, but do you have a manual boost controller?
Oh one more thing I remember now. On the 2LTE the computer goes into error if the boost is over 14.7psi or so, and it cuts the fuel. I'm not sure if the 1KZTE does this also. The way I (and others) have gotten around this is by t-ing in a air flow controller just before the boost sensor. We use this to proportionally drop the boost level curve seen by the boost sensor. It works really well. Basically tricks the computer into thinking the boost is normal, when you are actually running much higher boost.
Here is a little write up on how to do it:
Reducing 2lte egt's It would be exactly the same concept for the 1KZTE.
