yeah these cars have an adaptive system, meaning if you disconnect the battery looses it's memory, you then have to re-train the system, i.e. if give it heaps after you do this for about 50 K's then the system learns the way you drive and reacts accordingly, but 14L/100 km's is a little high, are you thrashing it / idling for long periods Some pics would be nice of wut you have done with the intake and exhaust I am thinking of inter cooling my TRD with a truck air dam ;), I'll post some pics when I decide to do this, my illustrious mech is going to do this ...
