hi guys i have an 06 motor in my 03 its the rev up motor. i have cai,catback stillen exhaust and mrev2 with spacer , i noticed my car after being warmed up about 5 mins i can floor it and the car bogs down , its feels like when launching it just bogs . same feeling , i noticed i dont have the 02 sensors hooked up ( which i wont bring my car to infiniti dealer again )!! i was wondering if not having the 02 sensors hooked up would cause a loss of power , and also what could be making the car bog down like that?

i was thinking maybe the throttle sensor was off somehow or bad?

 

anyone lol?
