That's what's perplexing.

Sorry, I've been lightly reading this thread but not sure of the specific discrepancies you're referring to. I saw someone who went from no SC to SC+E85 and had a big drop (expected). I saw someone who went from no SC to SC, on pump, saw a 10-15% drop (expected, especially with a PD unit).
Can you point me to the discrepancy that's perplexing you? I'd be interested to see as well.
My other post is mostly making a general statement - MPG readings are highly subjective. Even same person, same car, other variables can sometimes make it difficult to get reliable empirical results. Heck I imagine there's even a "new toy" factor - i.e. I'd bet everyone got worse gas mileage when they first bought their cars (disregarding break in effects) simply due to the fact you tend to drive your new toy harder. Over time we all probably settle down... until we put that new supercharger on. Over time I'd bet fuel economy with the supercharger will increase as the 'new toy' effect wears off
