might sound silly but do a good tune up first new plugs air and fuel filter, check your coolent ,oil change , o2's

i had a friend get really disapointed when his car kept falling off on the top end after the 3 pulls he checked his k&N and it was like filthy he did one more run without filters and was mad that the first 3 were useless.

let the operator know as much about the car as you can from cam to gears to fuel system before they start .

i actually borrowed a manifold from a shop once to test it against mine and for the $1000.00 diffrence in price there wasnt any noticeable diffrence .

also do you plan on timing changes or fuel pressure adjustments between runs ? (if so make sure tools are handy time is money on the dyno)the dyno operator can give you a wealth of info or he can give you a graph it's up to you. ask about shift points fuel pressure and timing as a minamum.
