Tunes -Racechip or BMS stage 1?
I'm debating over which tune to get for my x3 35i? Not looking for which one makes the most power but the one that has the best drivability and no issues. I would like to hear from others that have experience with either or both tunes.
Thanks John

I have the Racechip Ultimate and haven't had any issue thus far (knock on wood). I've driven over 1K miles on the "2" setting, which is seven settings above the stock setting it's shipped with. What's odd was on the "1" setting, it ran rough, but has been much smoother in "2". I'm guessing it has something to do with the air/fuel ratio. I also have an AFE Magnum FLOW Pro Dry S air filter installed.
It's been pretty responsive when needed. Smooth in Comfort mode and power delivery feels pretty linear. It's peppy in Sport and Sport+, although power doesn't feel as linear. I usually have it set to Sport+ with the shifter in D/S. I've hit 0-60 in 4.9 sec using the BMW Laptimer app on the iPhone.
