Default Is this Dyno accurate?

Well, a local shop near my home town held a dyno shootout today, and almost every had very disappointing numbers. The shop has had the dyno for about 3 months. The numbers were consistently low, so we're wondering if it's callibrated wrong or all our cars blow ***, let me know what you think.

d16y8 run 1 : 6.5psi, t3/t4 .50 trim .48 ar, 310cc injectors, walbro 255lph intank pump, hks fmic 2.25" charge piping, 2.5" downpipe, 2.5" test pipe, 2.5" greddy evo, v-afc -35 wot made 153.4hp
run 2 : changed wot setting to -5 (among other things), 154.4whp.

jdmb16a (170 crank) : i/h/e/larger throttlebody, chipped ecu, not sure what else.. 156whp (95 civic lx swap)

h22a : 8psi supercharged, 188whp

h22a : stock except aem cai, 121whp

2002 maxima (255 crank) : i/h/e, underdrive pulleys, 178whp

the 3 TT supras :
17 psi, 404whp
17 psi, 356whp
12 psi, 366whp

Did you go to a mustang dyno? A stock h22a puts out 190 (im assuming its h22a1, h22a4 is 200) to the crank. 15% drivetrain loss should yield 161.5whp, as far as the supercharged h22 it should have put out around 240-240ish whp. something doesnt make sense...

they could have the parameters set wrong which wood in turn make the numbers higher or lower than what they should. the dyno tech doesn't know what they are doing

Were the numbers SAE corrected, STD corrected, or just actual numbers?

Hrm... not sure if they did any of that correction. I don't even know what that means unfortunately.

After the pull the graph popped right up on the computer monitor and they shouted out the number.

I guess i'll have to give them a call sometime and arrange a trip with my friends, but first i wanna run 8psi hehe.
