I can't comment on the FC yet as it's only been a day, but I"m loving it so far. The car feels a lot lighter and responsive. I find the stock Mazda 3 sluggish on low speed & rev. Even my old waja had better pickup. But after the remap, it definitely feels alot livelier. I'm actually expecting better FC because I won't need to press down the accelerator for 2 seconds waiting to it to pick up anymore.

I did the remap at AE Tuned. Look for Mr.Chai. They are doing a promo now.
Wow, 380km does seem a little low. I'm on 80% city driving and I get more than 500km, and I don't have a light right feet. Might need to get something checked.
