No idea what experience you guys had w/ the "fix" but I've lost about 4mpg, even w/ deleting/tuning afterwards.

Before the fix, I could consistently get 44-46mpg on the highway, in the summer time, with the AC blowing cold. When I mixed in city driving, I'd be in the range of 42-44mpg.

Now, the absolute BEST mpg I can get (w/ a delete and tune) is around 41mpg--on a 'good' tank. The norm is somewhere around 39-40mpg. I've tried both the Stage 1 and Stage 2 tunes and I can still get nowhere near the economy I was getting before the fix.

What's been you guys' experience with the fix and fuel economy gains/losses?
