i recently jus purchased a pr3 ECU thats obd0. and it works with no problem but my motor feels like it lacks power wen vtec is engaged. almost as if it was bogging out . could it possibly be that vtec is actually not engaging or something else that i might be over looking. i had the wiring checked twice and its correct so i kno its not that. i have a 91 hatch w/ a d16z6 motor. any help would def be appreciated and repped. thanx
