An increase in power in a engine is a tricky thing ot evealuate and not a good measure of the engines overall performance. Smoetimes more power is gained by using more fuel, other times it's gained by better overall combustion efficiency, such an increase in the compression ratio. The transmission was clearly the biggest improvment, but the increase in engine performance may have allowed hte enigne to use a lower gear, where it previously would have unlocked the torque converter or downshifted. I still think overall the EPA ratings are somewhat suspect. A better measure would be to publush fuel consumption numbers for the vehcile when traveling at a steady speed, and when accerating from a stop to 60mph at a given rate, and holding a given speed up an incline. It would be much more objective than the simulated test cycle the EPA uses now. Replies to this message: explorerx4 (Sep 25, 2009 4:41 pm)

Replying to: motoguy128 (Sep 21, 2009 5:48 am) i don't care about objective. the real world difference is approaching 20%. pretty good with that.
