So basically I am going to buy a hand held tuner either SCT or Diablo sport. I want to be able to switch between octane level tunes back and forth. I heard the predator has 3 tunes for ever octane rating and SCT is 10x better, lol. Can I do the same thing with a SCT very easy? Overall I want reliability, usability, performance and what’s safe for my car. What are your opinions or recommendations?

p.s. Read online modular powerhouse sends two tunes for premium and supreme fuels with a SCT for $400?

 

they are really pretty much both the same. it just depends what the shop that you go to uses to tune. i have my predator and i love it, and if there are ever any updates i can just hook it up to my computer and download them, not to mention live datalogging if you have a laptop

 

if you want to mess with the tuner yourself get a diablo. they are more user friendly. sct is for people go get custom tunes or go to dynos because you cant really play with the settings without hooking it up to your computer and changing them and then loading them
