It only acts up when I start up the car, not when I've been driving it around and only on the 2.03 v2 and Beta 3.0 maps. Doesn't do it stock or on the 2.02 maps. Weird.
I took it to an indy shop owned by a former BMW Master Tech and he couldn't find anything wrong. I suppose I could have BMW do a leakdown test for some peace of mind, but don't want to pay for it...guess I'm not that desperate yet.
At first i was thinking that my hpfp gone,but after i reinstalled tune everything was allright even during hard accelerations
Don't wanna by new hpfp... Do you know how much is it?
