Here's your "crap". Not sure how I'm supposed to reliably add octane without driving to a "93" state. Let me know of a better way if you have one...
Don't mean to diss on BMW's engineering prowess with my post but it seems that the added boost from the ecu is giving other parts of the intake/exhaust tract some fits. Why wouldn't it. I'm asking for a major increase in one part of the power process deal (added boost from adjusted waste gate/fuel/ignition) while not improving another (physical limitations of the stock intake and exhaust tract). Again, I'm not disparaging the "brand", I'm just learning that the ecu reflash naturally exposes some weak links in the turbo-charged combustion process that I had not anticipated to be so glaring.
Back to your regularly scheduled programming.
