My car will be close to 13:1 compression and I need to know who can tune it on 93 octane. I called JMS Chip in Mississippi and they told me if they tuned it on 93 they'd take all the timing out. The will not write an aggressive tune for it. I eventually want 2 tunes the second for 109 or 115 octane fuel, but for now I'd like a good 93 tune that the car will still run good on. I'm willing to travel to a certain extent. I live in southeast Louisiana.
