So short story, up until my ride home from work yesterday mhd and xhp lived happily together in my 240 xi. I reflashed xhp yday during work to change some shift points which i've done in the past and on my way home last night experienced low boost, no more then 3 psi. Little did i know that the issue was with xhp and not mhd or a hard part problem.
So, strangest thing i found today. Obviously thinking the worst on a new to me just purchased car. There's something going on with xhp, when i remove xhp, my problem totally goes away and i'm back to my happy boosted self. put xhp back in, problem returns. keep in mind, they were working together flawlessly prior to my ride home from work yesterday. i did reflash the xhp during work yesterday to change shift points so i guess that's where this happened.
Bottom line, no xhp, perfect mhd/boost. put xhp in with mhd or stock, and i have no boost, almost like it's in valet (it's not that i can tell).
Any thoughts or has anyone seen this?

Is there something new literally as of the last day or two that after an xhp flash it restricts power/boost or limp mode.

Well, i never touched the torque nm values before but i read on another forum to lower them closer to realistic, in my case i did 800 for first gear and 900 for all other gears as opposed to the 1200 that came up naturally and after reflash, boost is back!!! So in the end, not sure if that was it or just dumb luck but car is happy again and so am i.

Very odd the way it all happened, but she's back to normal.
