I just got my new Predator tuner and was looking through the Performance tunes. Under Diablosport Pulley/Performance 91 octane tunes (as that's all I can get in California) if I do that one is there one that does the 91 octane tune with no pulley? On the web site it shows that there is, but in the user manual it doesn't really say for sure and I'm a nervous guy when it comes to downloading something I'm not sure about. Anybody have any experience with these tuners?
