Default MPG gone down, any tricks!?

Just had a new battery installed:

Getting around 44-46 MPG after installing new battery.
Was originally getting 56-58 MPG before the old battery went bad.

Any idea what I should do? Also, is the K&N air filter good for the Insight?

Foam and oil filter is not as good a filter function as paper element filters; and as the Insight has a very low pressure drop in the intake , any flow gains may be minimal.
The paper filter changeout time is a long term in the insight according to the service schedule; in fact the more clogged the better the filtration.

Trevor was it the 12 volt engine battery or the ima hybrid battery? Any chance they checked your tire pressure and dropped it down?

We are hitting around 107F this week, AC maybe affecting your MPG? I'd also be curious to know if they changed your BCM MCM versions? I was getting in the 40 MPGs range until I completey drained my freon from the car, vacuumed it back down and added the right amount of oil and freon back in, now I'm getting 53 in the city. Could do better but the constant stopping at lights kills me.

Edit: Almost forgot to mention my AC doesn't hiss at me anymore when the AC compressor cycles off, my wife had actually started calling my car the iron lung becuase of the constant hissing.

I switched out the IMA battery with HybridRevolt. I wonder if it's the tire pressure too. The AC has been pretty much consistent with the 56 MPG. I'm trying to think what else could be the issue. What PSI should I be at? They were nitrogen filled when I bought them.

Maybe they too have a quality control issue?

I doubt it. Matt is a stand up guy over there. I think it might be the tires or possibly something small I'm overlooking.

Trevor,
Is the MIMA display indicating any stray charging ?

I run between 40-45 PSI, if Matt did the battery then it should be the same BCM/MCM so that shouldn't have changed anything. Did you pull and install your battery or have Matt do it?

I had matt do it. I'm not sure what the issue is at this point. I'm taking it on a road trip next week and would like it figured out.
