Looking at the SCT site, they retail the same. If I don't get my hands on a used one by tomorrow, I'm gonna order a new one. Any suggestions as to who to buy from? Need some info ASAP. Thanks.
The X3 is blank and can accept 3 custom tunes, the SF3 has 3 canned tune and can accept 3 custom tunes.
I agree will Raul, you will get a better deal from one of our vendors if custom tuning is what you are after. However more than likely you will be sold the X3, so if you don't like the custom tunes you have nothing to fall back on.
But you continue to order custom tunes from our vendors.
It's the best money you will spend as far as upgrades go.
