I have recently had my car mapped and told that my BHP figure for my car is 340 @6.5k rev with 310 ft.lb of torque. At the Flywheel.
I then had it rolling road tested at another garage and was told that i am running 267 @ 6.5k at the wheels but got no torque printout.

Does this loss sound normal?

I say this as even the garage who rolling roaded it didn't know what the loss through transmition should be?


Any suggestions or further information would be greatly appreciated!

Thanks
Strat
