Best change was adding the overdrive. When I had the TH400 I averaged right at 9 in just regular driving. With the NV4500, I got 11 consistently. With the update to the heads and cam, I get high 12's consistently driving around town and high 13's on road trips. I was getting 6-7 with our travel trailer and now I can flirt with 10 if I take it easy. I use overdrive a lot when towing.
