Will a canned 93 tune automatically lean out my mixture to where it should be? Or am I going to have to learn all the nitty gritty about F/A ratios and do it myself?
I suggest anyone using a DSP/tuning device to at least understand the basics of how your car runs, and what exactly you're tuning and how these things affect one another. Otherwise, it's pointless and possibly dangerous.
