We have 9.6:1 compressions engines that are specifically programmed to run on 87 octane. Well, 9.6:1 is a relatively high compression for 87 octane, which means that the timing curves have to be conservative. Doesn't this mean with a custom chip, aggressive timing, designed to run on 91+ octane only, that we should see a noticeable difference with just a chip??? I've read reviews that chips dont really do much for the 5 speed cars... but those reviews were referring to Superchips and Diablo chips, which would have to be somewhat conservative for the masses. I have the opportunity to get a custom chip locally done, with alterations if I feel its not right, 3 positions also, but it will cost me. Wondering what you all think about this.
