I have a '00 R/T and I have yet to get more serious about the engine because here in beautiful North Dakota (very sarcastic) the best I can get is 91 pump gas.

My question is this, do the pcm's all require like 93? I guess that would pretty much take the point out of beefing up my motor if I can't get a computer to make use of it.

I thought maybe I could get a custom flash to tune it for 91, but I'm sure as hell not going to live here forever and I wouldn't want to pay for a pcm twice.

Any help would be greatly appreciated. Thanks!

you could try octane booster, but 91 octane should be ok, i dont believe 2 octane point should make that much of a differnce.
