Did some talking to people dealing in dynos and was kindly given information pertaining to the different dynos that are in M'sia.
Apparently, Dynos really do work differently, have different methods of registering hp and its pro & cons.
The info that I have are 2nd hand thus it might not be as accurate as I hope it to be.
If there are mis-info, pls chip in.
Dyno Dynamic & Dynamic DTS
