I'd get it tuned for 91, you are going to have a hard time finding 93 octane in most of iowa
I'd say this gas is good, real good for 93. Many old skool guys w hi compression are using it in their restomods. Al claims it tests 94 all the time.
Btw as far as I know there are about 8 or so term in town. Hard to keep track any more. Several pretty quick lsx's, a few t buicks, a evo that will be nasty, already seen it, a monster. Bunch of fox bodies. Then there's the awd dsm crowd w t eclipse and talons. We can always use another 03 person, I'm friends w most the street ppl. Ya we do things late mostly on fri and the next day. There's a car show on thurs early evening used to be real good not so good anymore but still around. It was at advance auto at 16th and williams. Of course there's the restomods etc. Just thought I'd give u a idea of whats around hidden mostly but there. H and W speed shop has recently opened, brian havlik is a great person. There is a new superflow dyno in center point (black widow diesel) owned by brian bunting. He's big into turbo diesels. http://shop.blackwidowdiesel.com/main.sc
