Yes I used a strip from front to back between the skirt and rocker panel.

my 4,000+lb GTO with a 400HP 6.0L (when stock)
was getting 30-32mpg on the highway (if I could keep the speed up about 70-75mph)
and that's with 3.46 gears
now, she gets about 23-24mpg highway

I have considered a T56 but those cost their weight in gold around here, and I have been planning a 6L80 swap with 2.73 or numerically lower ratio rear for a while now anyway.

btw,
your front tires are on backwords?
are those Mich Pilot Sport A/S?

Yes and yes. I swapped them a while back to diagnose a problem pulling to the right and have yet to swap them back.
