[QUOTE="RossKean, post: 1456861, member: 19880"] Same here, but no longer. There is only about a 3% energy difference between E10 and pure gasoline and virtually no difference between premium and regular. (More difference between winter blend and summer blend gasoline in northern climates. (Winter blend contains more of the lighter distillates like butane and has a bit lower energy content - a couple percent) I'll be interested to see how it works out after a few tanks. Still surprised that the CO setting does anything but I don't know what Ivan's map really does or how it uses O2 sensor feedback. I would think that for an '06, it is worth keeping the Ivan tune for the improved throttle response if not for fuel or power considerations. [/QUOTE]
