I wish they sold 93 up here, looks like every State soon is going to 91...sheesh. When I lived in Pennsylvania premo was 94, and some places had 96.
Do you mean that in the long run as far as injectors and such? I put down a 13.1 at Bandimere, this is definitely a record for this car at this altitude. With 91 octane in it my car runs a 13.56. 4/10's is a lot in regards to bracket racing so I am leaning towards sticking to what I am doing. Unfortunately, bracket racing season is over, so hopefully by next year I will be running E-85 and none of this will matter!
