How To Fix Misfire Issue On N54 Custom Tune 

I’m on E60 With port injection.

@@menjicar I have a question my cylinder 3 injector was not fully sealed, I tried to tighten the injector bracket bold and stripped the bracket bolt in half, half of the bolt its still in the hole for the bracket, even when i put older injectors with a seal in it there is still play in the injector keep in mind the bracket is no longer on, does this mean my injector hole is ovalled?

Both at high rpm or in a higher gear when really under load.

@menjicar right, slightly different to mine, I can drive mine really Hard in any rev range, but if I dare exceed 6900rpm it does the bmw bong and half check engine light, replaced my injector seals last year, I might replace no 6 injector and seal and see what happens

@@17t135i yeah if not. It’s 100% going to be the injector bore. I had to fix mine. Video coming soon

Hey did you ever figure it out?

Maybe next time 👀 mine has been holding on for a while now too

It worked for a while but issue came back. Most likely due to me running at 27 PSI Boost. Because it was fine at around 22-24 psi. Had to drill and make new injector bore. Was oval out. Made separate video
