I have only ever run 93. No race gas around me and the few times I went to the track they only had leaded which I don't want to run.

I'm really trying to see what she is capable of on pump gas. So staying away from the 100+ & E85.

AFR's tuned to about 11.0 with the meth on full.

Once I get the 450's installed I'll have to do a full re-tune and mess with the timing more to squeeze the last power out of it.
