Does anyone know if dodge has a mopar performance ecu for the 2002 5.9 4x4. I noticed production ended in 2000. Or will the 2000 mod work on the 2002? Looking to get more HP out of this engine. I have read that the aftermarket chips and tuners make little change in dodges performance.(not sure if this is true)



Current mods are magnaflow cat back, airraid air cleaner, goodhood ram air hood.
