Then I installed a supercharger (Maggie also). It ran great but at highway speeds (80-85), I was getting 8-9 mpg.
That sucked.
I only installed 35's on my new SUT but still am contemplating installing a supercharger. I found a brand new maggie in the box with intercooler for 2750.
You'll probably want to install a set of gears. Be prepared to kick a lot of people's azz out of the hole.

Why did u install the 4.86? What is stock? I had an excursion with 40's on it and I upgraded to 4.11.
