Stock GTP, combined city and highway. Quite a difference in fuel mileage. When I bury it every time I can in town, and cruise the highway at ~100mph, I get only 15.5 mpg after 200 miles. When I take off sedately and let the Yugo's pass me and keep it from indicating any boost on the DIC(giggle snort), I get 23 mpg after 100 more miles. Anybody ever wire a switch into their system so the supercharger never builds boost, no matter what the throttle position, unless the switch is thrown--like Mad Max? Or maybe adjust the bleed off system to engage even later, like almost full throttle? I was thinking it might allow greater throttle input(more normal driving) without the mileage hit until you needed it, or hit the dragstrip. These motors seem to be pretty torquey even without boost.
So far I love my new car, just gotta get used to paying the price at the pump. I'm used to raising hell every time I got into my Civic and it would still give great mileage, just not the performance of the GTP. I suppose I shouldn't complain as it only had 1.6l and I could get it down to 24mpg if I raced it allot.
Did I mention I love my new car?
