Isn't the Nistune program limited to the MAF reading? Is it able to do dool pop chargers? Or is this limited to only single pop charger? I like the fact that you can hook up a wideband and tune with the data logging. Makes it real easy to richin up an area. Very nice. Zem has the ability to do real time editing but not for hooking up a wideband. You must use the wideband on the dyno and stick it up your tail pipe.
