I never said I could out pull a duramax for obvious reasons. Second pulling goes by weight class. 5800lb super modified. A 2500hd has almost the same curb weight as a f150 even though one is a half ton and the other is a three quarter ton obviously depends on box and what not. both put 300 hp and 360 lb torque unless you are talking the brand new 6.0 hd which is more. I was just joking so no hard feelings. If you want to believe yes I did outpull a 2500 hd 6.0. Cuz if you have ever pulled its not all about whats under the hood compared to what people believe. So no hard feelings and glws.
