I recently upgraded my '02 WS6 with a Corsa and a SLP lid. Am I saving on gas milage? My car gets an average of 250 miles per tank. Stock, I used to drive from NJ to VA 250 miles one way, and I would still have a quater tank left. I haven't done that since the mods (since my GF graduated college) but still it seems like I am losing milage around where I live, which isn't too much stop and go. :shrug:
