SCT Xcal

They do sell X3's with 'canned' tunes - we just sell them with custom tunes though. You can get whatever tune you want - factory with just improved tranny, 87 octane performance tune, 89/91 octane, 93 octane or race gas. They'd usually all include improved tranny functions. Plus we can adjust idle and rev limiters to wherever you want them, for off-road use shut off all smog stuff plus a lot more. Updated tunes with the X3 can be emailed as can datalogs.

Hope this helps,

Don
