I'd like to know how much you did pay in US for "car dyno".
There are 3 motorshop in my area :.
-1st:1600bf (35$)/dyno. very old machine.
-2nd:3000bf (65$)/dyno but you don't receive dyno chart,only max power.
-3rd:5000bf (110$)/dyno and you receive dyno chart.
I know that 3rd one is very serious...but very expansive i find.
Conclusion:if,like i want,i go to dyno shop 5 or 6 times
(air filter,exhaust,throttle body,ecu,...)it finally 'll cost me
between 500$ and 600$.
What do think about?
Any experience?

Thanks,Mike D.
