i have a turboed b18c, it just recently had an aem ems put in and tuned. after driving it i noticed that it sputters when i press on the accelerator too much and the engine completely stalls out intermittenly. im going to get it retuned but in the meantime is there ne thing i can do to solve this problem. i already changed cap, rotor, wires and plugs, any help would be appreciated.
