Question About MAF Sensor

[windrunner408]

I have question regarding whether my MAF sensor is messed up or not. There IS definitely a noticeable way my engine behaves when the IAT reaches 80+ degrees F. What I am noticing is that while cruising down the road and IATs get over 80F that my required boost to maintain ~67mph goes from about 6-7psi on relatively flat level ground to around 9-10+psi. So my question is what could be causing this?? I have noticed that this WILL happen everytime IAT gets over 80F. Am I looking in the right direction by blaming the MAF sensor?

Cooler air is more dense and gives you more power, which I'm sure you probably know. For us here in the desert of AZ, it is especially noticeable. During summertime, I have noticeably less power, especially when I see IAT's of 120-130*F. In the wintertime, particularly in the morning when the IAT is 70*F, it is like a whole other animal.

That is good to know. Yea I knew that cooler air was more dense but am glad to hear that others are having similar results. That is essentially what I am seeing. In the mornings when IATs are lower, it feels like I have more power than when it gets hotter in the day and I just wanted to make sure I didnt have a sensor that was messed up.
