Yeah, tuned for the pulley & GM corp. requested the calibration. I'm familiar with the warranty game, I'm not asking for them to warranty the modified SC though.
No rev limits changed, nor any internal engine components modded. I can see if I had done a cam, or oil pump (basically any internals, then I'd expect them to not honor the warranty, but the SC has nothing to do with the oil pump nor is it even in the oil path. The Magnusun-Moss act puts the burden of proof on the manufacturer denying the warranty to prove that the modifications caused the failure.
