Nothing really. I don't believe you can adjust rev limiter (i think thats the same for both of them but correct me if i'm wrong). The tune for 91+ Octane is the same for both. If you're just concerned about putting the tune on, possible timing adjustment and thats it, certainly go for the PowerPup (I had one worked great). If you want a fancy display and crap like that, GT Tuner.
