That's what I just got for my 2005. X3 and a CTS. Just got the tunes from Eric at Innovative put in yesterday, MAN what a difference. It will bark the tires in the first 3 upshifts (1-2, 2-3, 3-4) at 3/4 throttle tip in. That's the most I got on it. May do it in the 4-5 shift. I was pulling out on a highway in traffic today after my girl got her first deer and I mashed it down a little and then got out as soon as I got to 70.
Don't have my CTS yet, it shipped but won't be here till Wednesday so I'm trying not to rod it too hard. I have a bullydog watchdog right now in the meantime (truck came with it).
