2007 Tahoe LTZ 5.3 4x4 Whipple or Magnuson

Not that I totally disagree with rebuilding, but the sloppy mechanics guys love high mileage ls stuff because the rings are well seated and the ring gaps have opened up enough to make it safer with boost.

Also, what was your gas mileage like before and after the supercharger out of curiosity.

Before it was 17-18 mph hwy. 10-13 city. 10mph towing
After 14-15 hwy. 10-12 city . 4.5-5.5 mph towing.. yeah that bad

Took off the sc. Did a dod delete vvt cam and some cyl head massaging.
About 17 ish hwy now. 10-13 city. 9-10 towing. And a lot less heat
