Stock X6M Perf from a 5.0 X6 w/ a tune??
Ok before I get too bashed I would like to state I did do a search & didn't come up w/ much beyond a a thread & 2 posts.
I'm a former M6 owner & current M5 owner who has the itch for an X6M BAD!!!
My employer owns several BMW stores & I'm entitled to all sorts of discount perks but after speaking to the local GM I was wondering how far off a 5.0 X6 w/ the M Sport Pkg Opt and the addition of a performance exhaust, intake & ECU upgrade would perform from a bone stock X6M. I realize theres a 150hp difference, not sure about trans or rear axle ratios but my understanding was that the M Sport Pkg on the 5.0 would about about mimick the X6M everywhere else other than the driveline.
So I guess what I'm asking is what would the performancve upgrades mentioned (intake, exhaust & tune) yield on a 5.0TT w/o affecting the reliability or making it into a time bomb? What did those upgrades cost vs the $22k base price difference between the vehicles?
All constructive thoughts & comments welcome!
Has anyone already done this?
