I am wondering if I had dropped a range or gear if it would have got better MPG? I was running 1,500 rpms at 60 with around a 5 psi boost in the hills but in 4th High it did not need turbo boost and ran at 1,700 rpms with the Cat 3406 engine. Just tring to figure it best HP/MPG range with this engine. I have 13 gears to work with. Mark H.
