Over inflate the driven tires. 40 psi to reduce rolling resistance from strapping it down. ..

Dyno with fresh air supply in front of car....speed inc sucks for fwd...your dynoing with egr in that building lol...

Garden sprayer with ice water sprayed on core...or leaky nitrous bottle and 1/4" copper tube....

Clean filter and britches

Before dyno day I would do street tuning and make sure you have zero kr from mid second gear all the through 3rd gear. I was dynoed in 3rd gear so what ever 6500 rpm is 3rd is, is what mph they stoped the dyno at. Don't be switching up you fueling or gas mixture.or anything after you find out what works the best for you. I didn't lock the converter or anything special. Just strapped the bitch down and let her have it.

If dyno shop insists their guy has to be behind the wheel,
make sure they hold on with both hands.

Our local shop guy never dynod a FWD car with torque apparently.

so it pulled the wheel out of his one handedness, and car went to zero in a no time as it came off the rollers.
