A re-map is programmed thoughout the rev range under different loads makign sure the cars is running its correct amount of fuel for the conditions.
As far as I can make out, a tuning box can only alter the amount of fuel and the timing of the fuel injection. Unlike a remap, it cannot change the fuel pressure. So from your thoughts Carlosmatey, the remap is going to give the ticking time bomb with the fuel pump.
Tuning box cannot do this.
As for over fueling, both methods increase the fuel at given times to achieve the extra HP.
Unless someone knows different......
Sh*t. Late for another appointment. Watch has stopped ticking.
OMG. Where IS that ticking sound coming from?
