I would really doubt it. Even their warranties for the engine are only if one of their authorized installation shops do it for you I think...the magnusson warranty was worded something like that.

 

The supplemental warranty covers the engine, transmission, and differentials against failure of hard parts. Fluid, gaskets, and electronics are not covered. Also, to qualify for the warranty the system must be tuned using only the included programmer; kits ordered without the programmer do not qualify for coverage.

 

Has any one on here installed one of these systems yet? Specifically on a 6.2?

 

This new guy said he did in the thread in the GMT900 section
