Has the fan part of the tune been modified from stock?

Are you running a 160° or the stock 192° t-stat?

The charge pipe is the normal location for the MAF on a Procharger inlet tube, it isnt the best location but it is it where PC puts it.

Also you really need to use a baro break out harness. If you changed the intake manifold to the 3 bar MAP then you are now using 2 map sensors. The MAF has MAP sensor in it, and the intake manifold has one as well. So now the ECM is seeing a baro signal and the MAP signal that is being influenced by boosted air.

The MAP in the MAF needs broke out with the DSX Baro breakout kit, or the baro/IAT breakout kit. Then the 3 bar MAP goes into the IM location. This gives the ECM actual outside barometric info as well as actual boosted MAP data from the 3 bar that is installed in the IM.

HPT tuners can read the codes as well, hook back up and connect with the scanner app. Then open the diagnostic data section and have it scan for error codes. The ECM in the Camaro keeps history of codes even if they have been cleared. They stay for soo many key cycles before it allows them to clear.
