I have a 2005 F250 4x4 that I put a 2000 24 valve Cummins in.All stock and running a 5r110 transmission. I have had it going for about 6 months. I pulled my trailer to Ga and bought a 1989 F350. It seems to pull ok but when I pull a hill and it kicks down to a lower gear it does not seem to open up. The boast will go to 10 to 12 PSI and feels like it will go to 21 to 2200 RPM's and hang there.I have checked for boast leaks. It starts good and no miss fire. I put a new lift pump on it when I did the swap and it runs 10psi idling and drops to 6 to 7 WOT.Fuel mileage is not what I was expecting 16mpg. Any thoughts on what it may be? Thanks
