Got it dyno'd today

[AddyDaddy]

Wanted a baseline done before I looked at tunes or anything. Did on a mustang dyno. The guy warned me the numbers would probably be lower than I see online compared to dynojet #'s. Said mustang dyno makes the car work for it, anyway
Corrected was 509 RWHP AND 494RWT
Un corrected was 5 less on above numbers.
Not bad for a 2013 stock

What was he talking about dynojets giving higher numbers than mustang dynos?

Those numbers are normal for mustang dyno's. Dynojets are slightly elevated 10 to 15% I believe. It's all about the calculation factors and that one is loaded and the other unloaded. What you need to focus on, is now that you dyno'd your car on that mustang dyno, any new upgrade (e.g. tune, intake, exhaust, meth)That you go back to that dyno for realistic "gains" number comparison. In other words stick to one dyno manufacture for accurate power gain numbers.

Yeah the shop is close to me, met owner in Costco couple weeks ago and he builds prototype race cars. So I'll stick with him so it's apples to apples on anything I do going forward and will be able to give real numbers for any tuner I go with and report back to forum

Something I was wondering is why was my torque so much higher than what factory says stock is and if that's so much higher why isn't my HP proportionally that much above what bmw says stock says? They rate stock torque at 502 at crank yet I put with 10 of that number to the wheels.

Do you have the dyno plot to show us? It might have been a little peak early on which often happens.
