Alright so, today I just realized why I am having a hard time getting the car tuned nicely. I have a pull through MAF setup and also have a BOV that vents to atmosphere. So the air flow that the MAF is reading is not actually want is going into the motor at all times. So what I am looking for is what would be best? Converting to a blow through MAF setup, placing the MAF after the intercooler but before the throttle body(ZZP has a kit)? My BOV is before the intercooler. Or would it be better to just tune speed density? Is speed density good for this cars, power, driveability, fuel economy? And if it is better to convert it to blow through MAF, who has the best pipe kit for the 2009 Cobalt SS?
Thank you.
