MAF was bad on my car so upgraded to LT1 MAF and translator, car will actually run and drive now but doesn't have the power it had before and has a hesitation when you first hit the throttle, The switches are On On On Off, first dial is set at 3 for LT1 Sensor no change, and second dial is set at 0 for WOT no change, do these translators come rich or lean out of the box perhaps? Mods are Champion iron heads, 50lb injectors, headers, down pipe, K and N filter, dual exhaust, and a Joe Lubrant chip
