So ive been noticing i burn gas quit quickly in my crx. I mean i have a 255lph pump, 450cc injectors and run 19psi, but i never really get into it anymore, and if i do its only for a second or two.. So last time i filled up i made record of my Mileage and then again when i went to fill up, and apparently i get 14mpg.. How is that possible because i know people with twice the size of my injectors making atleast 20mpg. Something with the tune maybe? or idk, anyone have any suggestions?
