Hi from the Great White North
 

Signing on from Southern Ontario. I love the concept of tuning a car to get more from it than the original design whether it be more power, or better fuel efficiency.

Welcome to the site.

What vehicle do you drive and what kinda mileage are you getting with it?

I drive a 1998 Acura EL. 388 500 kms turbocharged for 258 000 km, but tuned to run 16-17:1 AFR on the highway. My best L/100km is 5.88 combined, but mostly highway. I usually average mid 6-low7 L/100km in the summer. The efficiency really takes a nose dive city driving in the winter. This spring/summer will be the first with the current engine tune.
