Woohoo! My first victory! I FINALLY broke the EPA, not by much but I did it with basic cheap mods and just adjusting my driving style a bit.
When i first got my Box it was doing 26.18 then i changed the plugs and the airfilter and it bumped it to 28.55 and today when i did the new reading after just adding a can of STP engine cleaner, i clocked at 31.16!
