The HP result from my Gtech is different from the results from my local rear wheel dyno – why?
The Gtech usually gives HP values which are lower than a traditional dyno. Lower figures are due to aerodynamic losses incurred during driving, and increased rolling resistance of the tires on a real road surface as opposed to a smooth dyno drum. In any case, the power measured by the Gtech is truly the amount of power left to propel your car forward, which is really what matters when tuning a winning vehicle.
