yes,open pod filter (hks apexi k&n n others)
u can get a tulang ikan (in english dont know what valve it called) less than rm 10 n fixed it between ur actuator hose n open the valve a bit until it reach .8 bar (recommend u get a boost meter).
normal l2 got fuel cut when u exceed 0.8 or .9 bar.
dont throttle if fuel cut happens,wait for a while n it should return to normal.
