i am using the canned sct x3 mode and all i changed was the 93 octane, c&l intake, and turned off the rear o2's. if i put the fuel to "economy mode" will i lose any hp?

howarmat

yes i would think so

^^^Agreed.

The only real way to increase milage is to remove fuel & timing. Both of which provide extra power. I'd be willing to bet that it will only be less than one mpg difference between that and a performance tune.

howarmat

it will be more than 1 mpg difference....he wont be getting on the throttle near as much cause the car wont go anywhere!!
