They took about 3-4 months to send me mine and it was also 4.1, found out it is the incorrect disc which does not work for Hummer. Call them again and the will send you the correct one, 7.3, and schedule a UPS pickup for the old one.
The 4.1 part #20857425U will work with: Cadillac SRX/DTS, Yukon, Tahoe, Suburban, Big K trucks, GMC 900 and possibly other GM vehicles
and the 7.3 part #25956245U is for Chevy Envoy, Colorado, Canyon, Ranier, Rendezvous, Tahoe, Suburban, Avalanche, Silverado, GMC sierra, Yukon, Hummer H2, H3, Trailblazer and possibly other GM vehicles
