Tunes...

Whats the difference between the custom tunes under VXCF1(2006MY), VXCF4(2005,2006,2007MY) and VXCF5(2005,2006,2007MY)? Are the latter tunes the most recent, therefore the better choice for those years of truck? Also is there any write-ups on how to download them "properly" and upload them on the xcal3?

You will have to look up your strategy using your Xcal3 in order to determine which tunes to download and use.

ok, so those are basically tunes made for differently strategies? I'm interested in using the mild street or aggressive street economy, but I have seen that you have to make some adjustments to the shift timing etc so they will work properly. How am I supposed to know what to change?

[Evil Eye]

You should be fine with those tunes. The hotter tunes *may* require a slight adjustment to shift pressure, but most of the time, they work great exactly as they are. Load them up and see how your tranny likes them. Since the tranny has to go through a learning procedure, take it easy for a bit before romping down on it.

Thanks! I'll give 'em a try!

Be sure to follow the directions on the Spartan site about turning off the Anti-virus software before downloading the tunes.
