So the first thing you should do is go find the Dyno Database.
There's over 600 dynos from our M3's in there. If you want to compare Mustang vs. Dynojet, it's easy to do.

All Dynojet Dynos (all cars):

All Dynojet Dynos (only STOCK cars):

All Mustang Dynos (all cars):
http://www.s65dynos.com/DynoDB.php?dynoID=3

All Mustang Dynos (only STOCK cars):

Next if you want to see how much variance there is in stock cars, it's very easy to do from the DynoDB. After you have all of the bone stock entries on the screen, type "91US" in the search window. This will reduce the gasoline choices only to 91 octane. You can also type in "93US" or "94US" to see 93 octane and 94 octane as well.

How much variance have we seen? Nowhere near 50whp, that's for sure. The most variance we've seen on two different stock cars on the same dyno on the same day as part of the same dyno day was about 10-12 whp. Here's the variance I find when I look in the DynoDB for all stock cars.

Dynojet:
91 Octane: 312whp - 343whp (31whp delta, Avg 331whp)
93 Octane: 333whp - 350whp (17whp delta, Avg 339whp)
94 Octane: 343whp - 352whp (9whp delta, Avg 348whp)

thanks going to look at the DB. anyone know why my trq #s are high?..
