If you load the truck up with that much weight you shouldn't see a problem, and maybe even a little more than that, but I wouldn't push it too far. What are you carrying that weighs so much?

Yeah, that's what I was curious about too...

What do I carry? Here's a load of firewood...


Here's 2000lbs of fertilizer...

The performance tunes are only rated for the 2000-2500# range because the engine is set to run a little leaner to generate more horsepower. Adding more weight than intended will make your temps run much higher and risk all the damage associated with over-advanced timing.

The tow tunes are designed to help manage the temperatures and produce more torque by making the fuel/air ratio more rich. The timing is also slightly further back to keep from knock under the higher load.

Good looking truck , and yeah, you might be over the 2500#s with the firewood lol... and what longshot said makes sense to me. is that a full chord of wood or 3/4? sorry for the randomness...

Thanks That's probably a full cord, didn't bother to cube it all out lol

I run my 87 tow tune all winter cuz it doesn't make financial sense to be burning winter blend premium and idling all the time...but I was just curious where the 2500# limit came from.
