jetro Posted June 23, 2010 Share Posted June 23, 2010 mack al460 little or no turbo in low range .It pulls ok in high range , but still is not worthy of a 460hp stamp on the engine. it takes about 5 seconds after your foot is to the floor before it starts to build turbo pressure.

A Mack dealership will need to contact Mack and have step 12B software enabled for your chassis. They will then have to flash and reprogram the modules per Macks instructions.
