I have 67,000 miles just changed trans filter and fluid amsoil. When we first got there motor was hot and ran a 15.7 when it cooled off i could only pull a 15.5 at like 85 mph the kicker is my buddy just bought a 07 crew 6.5 bed lariat 3.73 stock and best time was 16.2. I just feel like i put alot of money into the truck for not to much inprovement. Any ideas or suggestions. I pull a trailer regularly and am not exactly easy on my truck but keep up with all the maitenence. The worst was my buddy with a 09 ram sport with crew cab 4x4 magna flow dual rear and valant cai ran 15.2 stock tune. Now I have to listen to him. Bottom line something needs to change so i can get back on top.
