Why a huge power drop off after 5k rpms?
...but your boost drops precipitously after 5k
something still doesn't seem right with your m157

Separate topic but i have Dashcommand app too, curious have you figured out how to get an accurate HP reading? It’s not a bad app for logging boost and IATs but the HP setting never works for me. Shows like 850HP on mine which is way off for a stock E63S / w212 obviously.

You're running too much boost IMHO for 91 octane and your IATs jump. I am sure your car is knocking, thereby pulling timing and creating dead spots and a weak top end.
Call Jerry at Eurocharged and get a better tune.

I Wish I had the money to pay for another tune but I've paid twice and just can't do it a third time. Last tuner told me rent a dyno spot and I'll dyno tune it. I did try to send him logs of dash command but every time I select just what I want it to record data on it records a bunch of other stuff and the tuner Is saying it's too much info and hard to tell what's happening. Just not happy with the tune I don't know what else to do. Tired of dumping money into tunes and end result is were I'm at now.

I contacted the tuner no response yet. One of he's suggestions was to rent a dyno so I told him give me date and time and let's do it will see if and when he responds. I just want my car to finally run right on a tune it runs perfect without it. Now instead of missing there are flat spots and after 5k it just goes so slow.
Have you logged fuel pressure? I was having a similar issue but in the upper rpms it ended up being one of my high pressure fuel pumps was on its way out car didn’t throw any codes til it got really bad. There’s quit a few people running ur tune my car has turbo back Downpipes and just keeps on pulling all the way to redline.
what was it felt like when it happened ? i mean, what symptoms during driving ?
