Towing Limit on Perf Tune

[Longshot270]

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.
