I have a 2011 STI Hatch with an Accessport, SF Intake, and Turbo Exhaust. It sat for about a month and a half while I was away and when I came back to drive it down the east coast, the battery was dead so I got a jump to start it and head south from Rhode Island. I was noticing some pretty awful performance and gas mileage over the 15 hour trip. I averaged about 16 mpg and was not getting the performance I had gotten before. I thought it might be from the fuel sitting so long, but I filled up the tank several times over the trip. My intake filter is in rough shape, so I plan on replacing it, but I wasn't sure if that was the problem. Should I uninstall and reinstall the Accessport since the battery died? Not sure where to go from here. I'm fairly new to the mods. Any help would be appreciated!
