Best tuner?
 

I'm told Diablo Sport Predator, please give me your experiences and opinions please, Thanks.

I say SCT Xcal 2

what he said, SCT all the way :pepper: :banana: : . never heard anything good out of diablow :nono:

it doesnt matter what software you use, really its all in who tunes your car.

I like the SCT interface better and I had problems getting Predator tunes to return consistent results early on (kinda random engine behavior from run to run) so I dropped Diablo in favor of SCT. I'm not sure if the predator is something I'd use as SCT has too good a reputation for me to ignore, their stuff worked great the last time and Diablo has been problematic for me more than once.

Other than that rant which is purely anecdotal, spike is correct. If your tuner knows what he's doing you'll see good things happen. If not, maybe bad things.

I'm sure we could all debate which software is better, and I'm not an expert so i couldn't tell you, but I would highly suggest looking to see what software tuners in your area are using and go with that brand. Both are good products, but go with what tuners are using in your area. Eventually you might need a custom dyno tune and if the tuners in your area are using SCT and you buy Diablo your going to be pissed off and vice versa

w00t! Thanks for hitting that point. That little glitch by itself cost me a major bucks in the long long ago.

My local tuner at one time (dont' know about right now) only did Diablo, then only did SCT... now I think they do it all but it still cost me money to switch.
