i just want to here other peoples thoughts on these 2.. im starting to regreat that i got the sct cause i paid somewere in the price range of about 400 or so for my sct. and didnt even check the prices for the predator which is in the 350 range...

know the questions asks did i actually make a better decision with the sct x3?

 

I think that the SCT is marketed more and that there are more dealers around. I ahve only heard good things about the other brand but do not know anyonw whoe tunes them or uses them. I have the SCT tuner only because Steeda.ca was using that one when I needed one and I have stuck with it since.
I have the SCT 2 and am not sure if I have to upgrade it this year as I will be needing another tune for the set up that I am looking at.

 

I use the Xcal3 myself. I chose it simply due to the Dealer Servicing and network. A friend of mine used the diablo predator on his stang, I'm not a fan of using it, I find the SCT easier to use. IMO
