1.5T VIT Stage 1 tune (Sport mode) gets better MPG than non sport mode?

[Civic_Si_Yes]

I recently started driving in sport mode and immediately realized that I got better miles per gallon than when I drove in normal mode. Normally I would average about 29 miles per gallon however once I started driving in sport mode it went up to around 32 miles per gallon with the same driving style and driving to the same places.

Why is this?

The only recent modification I did Was add a PRL SRI intake (street) Around the same time I started driving in sport mode. Do you think the intake has something to do with it or the driving mode since it adjusts the boost parameters and what not.

Driving conditions the same? With the sport mode the aggressive/higher revving shouldn't do anything but destroy your MPG.

Everything’s the same.
Same driving style and all. I get substantially better MPG. Today I hit 35mpg with everything the same
