Thanks for the response!
I had an accessport on my mazdaspeed6 a few years ago... But when I tried to load it on the 335xi but i had unrecognized rom, so i saved the ecu data. I then installed the cobb software on my mac so i could download the data from the accessport, to find out there is a firmware update available.. I updated the firmware and went back to the car and worked like a CHARM (as expected). I only loaded stage 1 on the car (its my chicks car) and I am thoroughly impressed! The actual flashing seemed slightly sketchy as my dashboard lit up like a christmas tree with lights (4x4 malfunction, the one that looks like the cars on a lift to name a few), thankfully once the flashing was done it all went away, and from my searching some n54 guys have had similiar issues, but they all said not to worry...
I don't know if this issue is inherent to all n55's or just the xi's but the oem mapping has a annoyingly touchy gas pedal, it acts more like an on/off switch, it makes driving the car normal a chore... anyway, the stage 1 map has corrected this issue, and makes the throttle tip in much more pleasant.
Powerwise, the car feels much stronger even if its not on stage 1 aggressive. My girl noticed the power and gas pedal feel immediately, I havent gotten to take it over 60-70ish mph yet.
Thanks Cobb! and fella's if you were on the fence about this tune its SO WORTH IT!
