Had no issues myself with Justin's work from twisted tuning.
But I think all OTS tunes are compromised now after going custom tune anyway.

Final revision E30 Log for my E90 N55 - 3rd gear - 6 speed AT with cheap Kinugawa turbo core upgrade.

Virtual Dyno reckons my 4th gear log is good for 454WHP
It could be optimistic, but it said my OTS Stage 2 + Tune was 327whp before I installed the replacement compressor housing.

In all seriousness, if you want your car to run at its best, get a custom tunes, there is too much variation with these PWG turbos, its somewhat easier with the EWG to get a good OTS tune.

Car starts then stalls

I have a issue, I had jb4 with mhd backend installed on my n55 I tried to take off jb4 because I wanted to get a custom tune straight with mhd and installed stage 2+ ots from mhd since im pure stage 2 turbo just for temporary until I get a custom tune and the car starts up then stalls right after, I tried to flash back to stock then it does the same thing starts up then stalls,so I put the jb4 back on to see if it would start and nothing change just starts up and stalls I even flashed the mhd backend to see if it would make any difference and no results. The codes im getting is 2c58 2c84 2c86 2775. I thought tmap and maf were faulty I swapped both out and it didn't do anything. Could this relate to harness/fuelings issues or needs a update on the dme?

Did your tuner flash "Custom tune" in MHD? If so, did he miss the burble option??

No clue a buddy of mine had it taken to the place it went for a different reason and they put there tune into it while it was there. Ran really good while it lasted. But being me I went in to turn the burbles back on and must have taken that tune back off. Gonna go back to have it done again but with the burbles. They did an awesome job as to the reason it went there it took care of my issue

which kinugawa core is this? looks really strong. Stronger than mine but I bought my kinugawa years ago when they only had 1 offering available. They have a few different cores now with larger wheels. Tune looks on point.

you can still use burbles options in MHD when flashing a custom map. You need to select your custom tune file when flashing. Obtain it from your tuner.

Yea I forgot to save it I guess when I reflashed I though I grabs the new tune but I must have grabbed an old tune that was saved. Owell we live and learn

From what I read, someone asked on that specific IG post, and their 135i is down for repair. That was almost ~2 weeks ago. Hopefully soon and some detailed map updates.
