ECU Programming

In HP Tuners, set the MAP sensor linear to 65.89kPa, MAP sensor offset to -6.35kPa, Boost sensor linear to 65.89kPa, and Boost sensor offset to -6.35kPa.

These are an intended upgrade for the 2.0 turbo Cobalt SS, HHR SS, Sky Redline, and Solstice GXP. The 2.0 LHU Regal does not need these as they come stock with 4 bar MAP sensors.
