Stage I EVO!!
I would say 13.1- 13.3 w/ the 19's 12.8-12.9 with 17" rims. Nice sound with the new air box too.
Headers in 2 months.
THANKS EVOSPORT!
The real gain in the MPG is the freeway driving I find? So the ECU maping would have the answer. Remember LEANER IS MEANER so maybe they leaned the fuel out a bit to get the HP UP, and yet not ping. I believe this would be the answer.
