bro...i think u need to retune ur ecu or else ur AFR will be running lean...
err... not vr sure... but if ur ecu self-learning type like siemens den ok lah... of coz, if u use too big throttle body and ur stock injectors not sufficient enough to balance the AFR, u might also need to upgrade to bigger injectors...bro...
do u mean reset my ecu?....coz mine stock ecu,can't tune ......
