I have just puchased this system and will be doing a full write up on my experience with it. For those who don't know this is the new tuner from SCT and is supposed to be very revolutionary in the self tuner market.
Well this tuner is amazing. Along with the real time data logging and display of six engine parameters at one time, It monitors 0-60, 60ft times, 1/4 et and mph and most importantly Air fuel ratio! The only downside besides the price is that in some model cars like mine you will have to move the OBDII port so it can safely have the plug in it while driving.
