How much better gas mileage should I expect to get? Considering my fan clutch right now is ceased so my fan is running constantly. I am getting 12.5MPG consistantly with the TSL's and Body Lift. With my 29" stockers and the body lift I can get 20 if I baby it but more consistanly will get 18. I know I will not see 18 with TSL's but 14 or 15 would be very nice and if an Efan will give me this I will have to do it very soon.
if you install e-fan for gas milage-i think you will be disappointed. if you install for performance only, i think you will like it. just my 2 cents. i have enjoyed the smooth shift with out the noise of clutch fan.
