I got like 20 when i was naturally asperated. I think it could have been better with a street tune (I mean a tune that was for idling and low rpms cause i run rich there)
Supercharged im getting an average of a little below 13... again waiting on my tuner to help. Should get something like 17 if not more. I run so rich at idle that i can't keep the car on very long in the shop or it will make you do funny things
Trying to figure out city milage... im just sucking down fuel... I need to pull a plug and see how it looks. 25 miles from ful to the 1/4 tank mark is just awful tho.
