yes i believe it’s 7”. It’s the biggest they offered for the f10. I had a hard time installing it for sure lol. It barely fit.

One thing I’m looking at is injector upgrades. People say the eu5 injector from the s63 have a little more flow and are better for running ethanol blends. Does anyone have feedback?

The f80 guys do that all the time, it's a pretty common mod over on f80post.

Are you still on stock lpfp, and have you done any weight reduction on your car?

Edit: PS, you need to change the title of this thread! You have a 10 second n55 5-serirs hidden under the title under oscillating rail pressure, lol

Was short shifting to 6th and adjusted my shift point to 6900. Can’t wait to launch on a proper track and hopefully not break anything.
