i just got injectors in my dmax today i didnt notice they where out untill i bought my tuner. when i got a tuner i would change my tune and get no performance. after a fuel filter and phone calls to PPE we narrowed it down to injectors but never had a problem running stock. have your dealer check them they are warrentied for 200,000 or 7years
