I am considering getting the Hypertech Power Programmer III because it looks like it gets the greatest gains with 87 Octane. One feature that Superchips lists is that it has gains throughout the rpm range with points at every 200 rpms. Hypertech doesn't say this anywhere is this a big deal?
Also I have seen some mention of the new Xcalibrator 2 chip from Superchips but I don't see it on their website, what is this?
