I have the SCTX3 tuner with 3 custom tunes already loaded up. I am coming from HP Tuners and DiabloSport experience so I was wondering how I could edit these 3 tunes I already have for 3.73 gears to fix the Speedo?
SCTX3; how do I change tune for 3.73 gears?

They would have had to set you up with end user adjustments. If they didn't do that you'll have to call them and have them either give you the adjustments or send you a tune with the adjustments made.
how do I know if end user adjustments were authorized?
do I need to connect the tuner up to my computer?

When you go to install the tune there should be an option about making adjustments. I can't remember what exactly it says, but it's an extra step before you choose to install the tune.
