I have already done some searches but couldn't find too many threads dealing with this question. Currently i am running a qjet carb and am getting about 8-10 mpg. I am thinking about switching to TBI and am hoping for an good increase in mileage (maybe 12-16?). It seems most people here do it for offroad capability and that would definitley be a big plus but i mainly want the better gas mileage out of it. For all that have done this conversions from a carb, how much did your mileage improve?
