Maybe with a tune, the extra requirements for fuel, or boost are showing you the start of an engine hardware problem that will eventually show up at stock levels.
Sniz has an excellent post on how to check for boost leaks. After that, I would try spark plugs. If it still occurs, have the dealer look at coils and injectors.
Boost leak test: http://www.e90post.com/forums/showthread.php?t=193077 |
I'll try that out thanks. Like I said before the car is driving great with the latest maps. The problem is the limp mode at the beginning of boost that I described. If there was something wrong or a boost leak why would it drive so well.
