The transmission itself accounts for only a small portion of drivetrain loss.

The difference in dyno results is mainly between a mustang dyno (heartbreak) and a dynojet.
Mustang's typically show about 145-150 and dynojets between 165-170 for a baseline.
Dynojets are more likely a more accurate representation based on what driveline losses SHOULD be from BHP ratings, but for some reason people like mustang dynos for gain comparisons and think that for showing gains, they're more accurate.
Go figure...
If he got 206 whp from a mustang dyno, that's pretty significant for 91 octane (especially canadian 91) and could be showing good gains for ITBs.
