now the bms pbx, worth it. no hp gains, but the throttle response really is what you will read. feels almost as if you're driving on DS mode but my mileage shows only .1 less at times, .2 more at other times. i put it back to map 0, stock, this morning on the way to work. and wow, felt like i had to really step on it to get the car moving.

you WILL began to get use to it's snappiness, but its not a bad thing. when i want to pass someone, or give it a little go, it'll move to my foot, not to the usual lag you get on the n52s.

hope that helps some!
Interesting, seems you like it do far ! Do you feel this snappiness across the range or is it just more upfront (lower revs) and then it "makes up" for it at higher revs, meaning you lose some of the linearity ? I'd think so since no HP gain, but I agree stock it does feels slow at lower revs so trade-off is prob worth it. I wonder what fuel mileage effect you'll experience, maybe share that later. A snappier pedal should ask for more gas but that's another unclear effect from what I've read.

Thanks for sharing.
