I have a 13 GS and have been looking at performance packages from Lingenfelter. They want $11k for a base 600hp supercharger setup.

Are there other performance shops within a 100 mile radius of Detroit that offer similar packages I can use to compare and read reviews?

Thanks

Pretty sure that the e-force they install does not void the GM warranty, and why the extra money over some other shops.

As for having a E-force installs (1591/1575 is dry sump, the kit is $7K on amazon, and you can have a shop install it for under $2K. The down side, this will void your GM warranty depending on the shop that does the work.

Put a blower on and then file a claim with GM for a driveline or engine issue and let us know how it turns out.

^^^I agree. If the addition of any blower doesn't negatively affect a claim filed under warranty for engine or driveline item(s) that go bad....
