According to the supported vehicles page, if you have the 4.6L motor then it uses an E67 ECM. That means you can indeed tune it with a FlashScan V2, V1 will not communicate with the vehicle.

I dont know what transmission that car uses, but if it uses a T42 (try selecting T42 from the read window and reading it out) then you can tune it too.

can i disable or raise the speed limiter

[ScarabEpic22]

Umm yes, its supported so you can adjust fuel, spark, shift points, speed limiter, rev limiter, etc.

Do you own EFILive already?

Yup then just make sure you're updated to the latest software and firmware on the main EFILive.com downloads page and read the ECM and TCM out.
