Helping a buddy out with his 2010 HHR SS and I'm noticing quite a few changes with regard to MAF, injector/fueling settings, MALT and cams.
Can anyone tell me if the changes related to the MAF/MAF Frequency and injectors/fueling has to do with the cam settings for emissions reasons?
Anyone ran into this? I can only assume the same general changes were made on the 2010 model LNF variants?
After doing some searching, I've found posts that mention putting the cams back to the 08/09 settings and that it would help the car tremendously with acceleration but wouldn't the MAF/injector settings also need to be changed?
