Hey, Currently driving a seat Leon TFSI, Bluefin chip remap to 240bhp (2005 on 55 plate) and bluefin chip was done by previous owner. I love the car, but the MPG is a real issue. On a long drive I get about 25mpg 30mpg max doing 62mph with cruise control on. Around my area which isn’t a busy city I get around 17. Would a Diesel Version of this car be much better all around and more beneficial? On a full tank I get about 270miles. Hoping to go diesel if it’s worth the change. Any information will be very helpful!
