Are there any tricks to squeeze out some extra ponies on the dyno? Tire pressure? gas tank level? operating temp? anything?

 

thats dyno racing and pretty high school but: more air in the tires and/or lighter wheels/tires is the biggest thing, higher gears (numerically lower), and keeping the stock 10-bolt. other than messing with the tune via an MAFT or custom program i think thats pretty much it.

Ryan summed it up...aftermarket rearends rob power, people sometimes dyno with slicks...they rob power..4.10's rob power...etc etc etc
