Dude, dont be shocked.
Its really normal. That much of horse on wheel is pretty adequate for the altezza for daily driving. If you want more 'gila', then u would need forced induction or transpant lah..
FYI, dynos gives an indicative reading and it varies from one dyno-meter to another. This is because different brands have their own corrective factors introduced to represent drivetrain losses. That means no 100% accurate reading lah!!
However,also remember, the hp at the flywheel can usually be 15%-30% higher than the rwhp. Then again, this varies for different car types.:shades_smile:
