I have a 2005 Si.

I have a really good performance shop right down the road.

I went in today and asked about modding the car for better fuel economy and the guy knew exactly what I was talking about.

They suggested doing the Hondata K-series ECU refresh with economy settings.

The one time flash would run $295, which isn't too bad at all if it works, plus around $150 to install a cold air intake. Right now I average on my longer trips around 29 Mpg driving between 65 and 80.

Has anyone else out there done this mod? Anyone have any actual results from tuning their EP3 Si?

Thanks!

Ben
