Yeah, that doesn’t sound right to me. I don’t drive mine much anymore, but when it was my daily I drove 75 miles a day in heavy traffic, I have a lead foot, and still routinely got 27-28 mpg like clockwork. On road trips 30+ cruising at 80. I have I/H/E, RBC, with Ktuner cookie cutter tune, but it was about the same stock.
