I have an SCT3 and was wondering if you should do updates with SCT as you would with a home computer with windows update. I thought that an 05 GT with an SCT tuner a year old, might be performance updates for the programer to, well maybe.
Anyone know or thought about it?

call sct and talk to them about any updates they might have

plug it in and see if theres a new update.

if u got a tune in your car, you can stick with the version u got till u get a new tune, that would be on the newer version.

it says in your instructiosn how to update it

Are you talking about a firmware upgrade? If so, just be sure you return the vehicle to stock before you do any upgrading.
