I have researched a few times on here and on sites about which is better the Xcal2 or the diablo Tuner????Everyone seems to have mixed feelings on this and really I want to hear from any1 and every1 and get to the bottom of it because I dont know which I want. Help me shed some light.

If you plan on a S/C and to bolt on the hell out of it get a xcal2. Plus I'm not sure if the diablo's got a two step> that alone made the x-cal2 worth the money for me, but it really depends on your mods, present and future

Yeah I was going with a S/c, but it fell through so I have to wait a little longer but I need something to hold me over, so I am going with 4.10's and a tuner......I have a good amount of bolt-ons so I guess SCTx2 may be route to go.......

I got the tune file from the shop I got my tuner from and when my 4/10's get put on all I gotta do Is adjust my street tune and my speedo will be adjusted

Ok so if I get the tuner before I get the 4.10's I can jus plug up the tuner and change the speedo cal just like with the diablo right?

and also when you first plug it up, it will save your factory tune like the predator does so if you sell your car you can take everything off and load original tune right

**** sorry I left this out...what exactly is the 2step

blueherd02gt

yes it does save your factory tune and yes you can get the tuner before you get the 4.10's thats basically what I did

I hate to say it, but one is not really gonna give you more power than the other. They pretty much do the same thing. Go with whatever your local tuner uses (or where you're getting your supercharger tune done). I had an Xcal II, but switched over to a diablo because thats the software the local tuner uses and I haven't noticed a diffeence in the power. JMO

Yeah im not wrried to much about which gives more power, just which has more capabilities.....and whats the 2 step that the SCT has?
