downshifting on dyno

Anyone know how to make a 95 stop downshifting on dyno?

can get it up to 4k and it still downshifts. Anyway to stop it without tuning? I need to see where the power is at

start at a higher speed so it doesnt downshift? im not sure what type of trans or gears you have but for my 4L60E and 3.23's i think somewhere around 70mph was when the pull was started.

A method I use that works most of the time. The key is most. is to tap the break just before you go WOT. It has worked for many cars, but again I have had a couple that it did not....
