I am new to this site already have adjusted my driving style and aired up my tires and got the volvo up to 30mpg from 25mpg. Hoping the wheather warms up to see how high it will go without any mods.
I don't haves scan gauge but I have factory instant mileage on dash that works ok. I need to look to see if I can block air intake in front without blocking aftercooler for turbo. I amalso looking at redirecting intake airfrom front of car to engine compartment to speed warm up
