What exactly is the si trim? Does Stillen have a higher power version now or is that something you get through Vortech? Also, just curious, how much mpg do you lose from the SC always spinning? I already get bad mileage because of the 4.08. Figured that could actually improve a bit potentially or not get worse with tt since I would lose the 4.08 gears.
