If you could even keep your foot out of either setup enough to matter....



Turbos in general but it swings either way depending on tuning. Parasitic losses are lower overall which helps (it takes less demand from the fuel system to make the same power on a turbo compared to a supercharger) but other things come into play. To be honest you really have to compromise because it's too much fun with boost on hand to worry about how much fuel your burning...

 

ya im having that problem with my new exhaust and tuned to lvl 3 on my edge.

 

I love turbos at high altitude. A supercharger not soo much.

Turbo any day of the week.
