Well I finally got sick and tired of the SVT randomly stalling, hesitating, and hunting for idle. I shelled out $375 for the SCT Xcalibrator 2 tuned by FocusSport out of California. Needless to say this is something I should have purchased long ago. The car had no balls below 4k and when the DSI finally kicked in at 6k it would pull strong up to redline. Now the car's feels strong across the entire rpm range. FocusSport revises the DSI activation point and kicks in a bit earlier...so now it no longer sounds like I have "mad VETEK, yo" when I hit 6k. As far as I can tell (won't really know until I drive it tomorrow), the random stalling/sputtering/hesitation issues are gone as well.

So for all those SVTF owners on TR considering this modification....DO IT! This was definately worth the money.
