Went to a local HP tuner a few days ago and got this as a result. A few guys on the FB page expressed some concern and I figured it best to go on here and get more opinions. So please let me know what you think. for the record its an 09, auto trans and factory MAP.

unfortunatly i cant figure out how to post a pic of the graph, but its posted on the Chevy HHR SS Owners group on FB. thanks.

 

Factory MAP ? Not sure what you mean by that.

 

Factory 2.5bar MAP sensors as opposed to the upgraded 3bar MAP sensors.

 

Gotcha. Tmap sensors.
