91 Octane & Hypertech III

[trever1t]

Is it ok to run 91 octane with the 93 octane program? I cant hear any pinging but i'm not sure if i would over the intake and exhaust sound! I have been running it on the 87 octane program with good results but want to try the premium fuel program.

 

Anyone?

That's what I'm doing, I think, mine is programmed for 93 octane and I run 91, no big problems. But don't hold your breath the performance is exhilirating!

Did you notice a big difference from the 87 octane tuning? I have picked up a little bit, maybe. Not a huge difference so far. Headers go in next saturday, hopefully i'll feel those!
