well after a boat load of tries i just cant seem to make any bottom end power on this thing-its just a pig-no traction control no torque mgmt no kr- its just a gutless slug under 3000rpm has anyone livened these things up?my tune is way better than factory and im coming from a duramax but this thng barely chirps the tires from a start is there any help other than a leafblower strapped to the intake?
