nice one man ill order one of them. if i had the money id get everything now just a bit of an eager beever the JAM ecu is plug and play. removes fuel cut, increases RPM and adjust fueling so im led to belive. i also read that its fine to run them at stock boost as they have fuel settings that adjust depending on boost but it does recomend a fueling check... as far as im aware you cannot change the map as such, they are just a bit more aggressive than stock plus the other things mentioned. apparently JAM and various others did these ECU's for toyota demo cars etc originally ( key word being apparently ) cant belive everything your read i guess
