I finally decided to go BM3 instead...can't justify 20hp for 1k. At the price you got it it was definitely a no brainer but the least expensive I could find was 925 plus 150 for install.

I would have gone your route for sure if I didn't get that deal. plus it seems so easy to install on the car. I'd say there is at least a 30-35hp diff between the two. |

BM3 will make the 50i in sports mode very similar to driving a stock X5M not in sports mode. Except the exhaust ofcourse. Very smooth and uniform.
RC was just giving a boost. It was not always uniform.

Where are you going to do it? I want to dyno mine again so maybe we can meet up and do it back to back.
I would take your computer with you and make sure you get a stock run and a tuned run to measure the true gain.

It’s probably right cause I believe that’s reading crank Hp so with your tune and mods your easily making another 100 hp.

Car ran much better with the new plugs but the hesitation was still there. Someone suggested the xhp transmission tune to raise the Torque Limits and shift faster. Now I have no hesitation and the car feels faster and smother. X5 xDrive35i (F15) SAV Stage 2 - Gear Display in all Modes - Torque Limiters removed - Reworked Shiftmaps - Altered Shift-Strategy. Choose from 3 different Shift-Speeds with the DEC Switch. Also fully compatible to cars without DEC - True Manual in M/Sport and M/Sport+. (no automatic upshift at RPM limiter) - DSC OFF and DTC now use Sport+ shift program - Adjusted line pressures above 400 ftlb for tuned cars |

How much was the xhp stage 2 transmission tune? Are you able to pass emissions with the ER catted downpipe?
