PFC users!! What's your gas mileage like?

I've been getting real crappy gas mileage after installing the PFC. Been getting at least 20 mpg in city, and 24 mpg in highway. I use to get 27 mpg in city and 32 mpg in highway. Funny thing is, when I dynoed it. I check the a/f ratio during idle and it was at 14.8 - 15.3. So it was running really lean, not rich.

mine is about the same, my a/f is around ~13.4:1 as opposed to like ~15:1 in the low end and ~12:1 in the top end with the stock ecu.

its all in your tuning...hit the dyno shop and have them lean it out for less load....you dont need 14.63 a/f while just cruising...only at WOT

I get better than stock... went a trip a few months ago, started in San Marcos(sp?) tx, filled up and didn't stop untill I was past Oklahoma city, over 400 miles away. Was getting 36 mpg.. I get 28 now, all my driving is freeway thou. That 36 mpg thou, I was going a steady 80 the whole way.
