How time flies. Have not been doing much with the bus but short trips. Fuel mileage has been about the same 9 mpg but the power is awesome. I have a spicer 5 speed to swap out and that should help. Have an egt gauge to install just been way to busy with work. I have to admit it is fun to pass a big truck on the interstate and see the look on there face.
Thanks again Joe |
