Went out this AM to the other vehicle, which is an hour away from home, so I thought this would be the time to check all of the parameters out from the AeroForce gauge. Average speeds were between 65-80 mph in OD. No laptop, just pen and paper, oh well, I did get readings. Some of the results that I am posting, I don't fully understand, and maybe the forum can guide me along or direct me to where I can obtain more info and a better understanding. Remember I have an Auto 08 HHR SS, so there may be some numbers that would differ from you manual guys, I would assume. No dead stop WOT's or Passing gear WOT's as the turbo is not operating correctly due to the BPV malfunctioning, which should be corrected in a week or so when I receive the Forge unit. So here we go.......

Well there you have it, I took the readings in the order that they appeared on the gauge, I left boost readings out as I produced very little boost during this log event. Feel free to comment or not no comment just thought these findings were interesting, now to understand some of what they mean........still thinking about the custom tune in the future............................................ ...................................Tom

That one should be close to zero or slightly negative, the intake is causing the ECU to add gobs of fuel, you are running lean so the system is correcting for it. It's adding 16% fuel.

Put the stock air filter in and see if it gets closer to zero after 10-20 miles.

The rest look fine for cruise.

yes in that order and I failed to mention that I cleared all codes when I got on the highway, so the LTFT was reset to "0". I will put the stock filter back in and see what happens, thanks for the tip....appreciated............
