Hey all, I was recently given a K&N high flow pod filter in great condition. My boss at work was going to throw it in the trash, so I took it and fabricated a semi-cold/cooler air intake for my '03 2.4L Liberty. I have more power, definitely, but my gas mileage has gone down to 25 hwy, 21 city. I was getting about 25 mpg city before. I believe the filter was originally for a truck. Is there anything I can do to increase the efficiency of my vehicle? Do I need to mod the computer as well? I know what to do with carburetors, but I don't really know how fuel injected vehicles adjust. I'm thinking about a muffler delete too, would this help the flow if air and gasses through the engine or just make a lot of noise?
