Did you ever receive a response to your questions?

The reason I'm asking is because I own a 2004 Chevy Tahoe Z71 with a 5.3L.

I have installed the k&N 5700 Series Air Intake, It also has a modified exhaust, and Off Road Package.

I haven't purchased the Predator Yet, but I'm thinking aobut it. It would be the same as yours is the U7193. But I don't want to waste $325.00 plus tax if the predator doesn't do anything?

There have been issues with some 4.8 motors on older revisions. Your 5.3 will be fine and will pick up a solid 15rwhp.

Thanks
