What a crazy weekend that began on Wednesday with Sunday L'oe show cars rolling in and the Saturday Red Horse Pottstown Nights show.
The most power winner of our L'oe Show Dyno contest was Austin with his 91 GTI 1.8L making an incredible 512whp on our Dynojet in Pottstown! The AWD testing was on our Dynocom currently in Birdsboro. The winner for our choice favorite is Jason with his VR6 swap Cabrio. Beautiful car done to perfection and even passed California emissions. That's a mission!

This is an unusual and cool project in for us to tune. Why not drop an EcoBoost into a 1970 Ford Maverick? That's going to be fun.
