drill out the ball in the throttle shaft and back out the screw a bit
adjust your aneroid valve so it gets rid of the fuel supply delay to make it more responsive ( the aneroid's function is to limit fuel until the turbo spools up. Its behind the little tin cover beside the throttle shaft).
shim the governor spring
change the fuel pump button (I think its actually called an 'idle plunger' or something). This is the biggest bang for your buck. Its not that hard to do but I can't recall the specifics because its been over a decade since I did this. A few hand tools are all thats required to pop the cap off the end of the pump then a socket and needle nose pliers to pull the stuff out. The 'buttons' are stamped with a number on the groove where it is narrower and the lower the number, the more fuel pressure. The numbers go up in a weird sequence if I can recall --> alternating between the increase of 2, then 3, then repeat --> like 5, 7, 10, 12, 15, etc. Depending on how far you want to go, guys used to take whatever they had and drop the number by 10 or 15 and it was pretty safe. Just be sure to have a pyro (that works properly), be sure to warm it up properly because that extra fuel will score a liner much quicker when not warmed. Do not lug the engine - drop a gear soon as there is enough rpm room to do so.
