Any of you had issues with getting the supercharger serviced under warranty (either normal or CPO) after doing a pully swap? Especially for the dreaded "clunk" TSB campaign.

I am thinking about the ETG group's full flash w/pully and my car is still under factory warranty until 2/2020 or another 78,000 miles (which ever first).

I am concerned primarily with the isolator issues that some are now experiencing.

 

Well. the tune might not effect the warranty, but the new smaller pulley might be an issue since they could argue that you may have damaged the snout when you pulled the old pulley and pressed the new one on. on the other hand most of the pulleys would have to be measured for anyone to tell that they are smaller.

 

Except that many of the pulleys change color during the process of heating them for installation.

 

That is exactly my fear. An obvious non-stock pully would raise eyebrows.

If anything goes wrong with my Supercharger I think they will not honor the warranty claim.

 

Not sure how that would go. Wish I could be more help. I have the tune and pulley (and, and, and), but haven't had any issues getting extended warranty repairs (none supercharger related though).

Would never go without at least a tune. Even if you skip the pulley, the tune really changes the character of the car and needs to be done. Trust me. The pulley adds power/torque between 1500 and about 4,000 rpm. The tune adds it EVERYWHERE. So now, I actually have more torque that I can typically use without TC intervening and I could probably go faster down a twisty road without it.
