On today's episode of what the heck is wrong with my BMW now...
To start, I have an ECU with Bootmod3 (Stage 1 93 Oct.) Bootmod3 8-Speed TCU Tune, Downpipe, Chargepipe, Muffler Delete.
Have had this stuff on the car for a while now, do normal maintenance, and some to keep the car running as one should any car.
Today I noticed when accelerating from a red light or stop sign, no matter how much throttle I give it, it hesitates until about 4k RPM then acts as nothing happened. Originally thought it was the tune, so I reflashed both the ECU and TCU. Same issue.
I should also mention, I have wastegate rattle. Could this possibly be a result of it getting worse?
No check engine lights, nothing blown up that I can see. Reading a few other posts like this, they all seem to be boost leak related but I wanted to get another opinion on my specific case
Here are some logs I was able to get (they're not the best)
