If I remember correctly you didn't have much hair to begin with! jk

I think it is time for boost a pump!

lol maybe but i seriously doubt this is fuel related as fuel pressure doesn't drop at all at the time of misfire..

Well I guess you will have to look into one of two things, #1 grow more hair to pull out, #2 I think someone said a while back that it could be internal something to do with the cams or lifter, something like that.

Just looked at logs, boost was at just 9-10psi at the point of misfire...boost a pump won't do shit in this case, fuel pressure is solid

This is not "limitation" of fuel or ignition 100%, something else

Has no issues holding 18psi at lower RPMs and no issues anywhere 1st and 2nd gear

cool. I'm in my 17th week of wait time. Dying to get them in the mail and installed ASAP. I think I have Trevor's DSS axles going in this weekend to keep the mod bug satisfied.

Hey guys, so check this out. I have a 2008 335i 6mt coupe n54. Purchased the car about 8 months ago used with CPO and Extended maintaince plan. Started hearing the heavy rattle dropping down in rpm. Took the car to my dealer, Competition BMW Smithtown (awesome dealer), and the same day i dropped it off they called me and basically said, yeah were giving you two brand new turbos. I was pretty hyped and im picking the car up tuesday. Been seeing alotta different comments on how it feels when you get it back, keep in mind the car has 58000 miles on it and the clutch was just recently replaced also. Gimme some heads up on how i could have some fun on the drive home lol.
