First thing first is you need a pyro, cause when you turn up the pump your EGT's will be way higher and will melt your pistons.
There is a triangular cover on the passenger side of the IP. Take off two of the bolts and loosen the other and swing the cover out of the way. Rotate the engine (if you have to) to see a allen screw. Take a good 5/32" allen wrench and turn it up one flat at a time, and then drive it. Start with one, if its not enough and your EGT's are ok, then you can turn it up more. A "flat" is one side of the allen wrench.
