What are dyno tricks?
I agree...but having personally done it on an LT1 just to see the gain (very noticeable gain on the dyno)...I wouldn't ever claim that engine made that power all the time as it was in a street car, and I was just curious what to expect.
J/K 
A couple things though. We check tire pressure most all the time before running a car.
We'll also pull the elbow off certain cars. BUT, we'll let the owners know. We do it on higher power GTOs, on higher power LT1s. Both, because the elbow is a significant restriction, and being able to show the customer "look what pulling your elbow off did" is both an upsell and a sort of R&D for us. I've seen 25 rwhp pulling an elbow off certain cars.
Is having people sit in the trunk of a high power FI car a dyno trick? After all, it does make more power. It lessens the wheel spin.
Anything more than 32psi in the tires will not show any more power usually. If it does its not by much. Keeping the tires at around 32psi even a slick will keep it from running warm and seems to not wear the slicks out as bad.
I have one of the lowest reading dynos in our area. A loading dynojet. Who cares, its a tuning tool. If the car only made 415rwhp in a 6 speed f-body big fing deal.. it still came damn close to the cam only records first try out with plenty left in the chassis/weather/weight.

Wait, so you don't see a difference between someone sitting in a car trunk to lessen wheel spin and someone fudging numbers with a correction factor?

This might be a dumb question but when doing a pull what rpm should the pull begin I assume from 2500-2800 but I see some people who start at almost 4000rpm will doing this mess with the max power?

-Manipulating weather conditions/changing correction factors
-Putting 40+ psi in the back tires
-Putting smaller wheels/tires on the rear
-Using aluminum flywheels but not claiming the car has one
There's quite a few other dirty tricks, but I'm not going to post them and give anybody any new ideas.
Sadly, there is a LOT of very well known and respected shops that pull these tricks to inflate numbers for the internet to see.

I wouldn't consider smaller wheels and tires a big deal unless you never run on them. Will my numbers be illegitimate since have stock 245/50-16 tires that I keep on 35psi? No.
Basically tricks fall in 2 catgeories: the operator messing with the correction ad the other is when you mess with the car itself (like pulling belts, filter, and putting on wheels/tires that you don't usually use).

i've done this lol!!!!!! put a pill in the end of the bottle and spray on filter
i've tried freezing the filter with nitrous before too, but it didnt help
Also, if you shooting for higher peak on a actual nitrous car, waiting to activate the nitrous until higher rpms (say, 6000 on a 6600 pull)will yeild a larger number on a stalled auto car too.
as you can guess, we get bored at the shop sometimes

I know for a fact spraying nitrous in front of a car will pick it up. When I had my dyno I was doing a dyno day and we were joking around about it and tried it on a colbalt ss it picked 25-30hp just misting nitrous in front of the car.
