So i just picked up a 2007 BMW 335 which had new injectors fitted for about 18months ago, real BMW injectors.
Today i uploaded a stage 1 E30 MHD OTS map to the car and now it flies!
I did 3 pulls with cooling runs in between and i hope i eventually can post a link to the log..
Currently im to "new" to be able to post links..

I did find a tutorial on how to deciper the logs and according to that the AFR should spike the instant you step of the throttle.
In the log it takes a while after i had released the throttle untill the AFR spikes, also bank 1 and 2 doesnt really spike at the same time.

Is this something to be concerned about?
The injectors should be basicly new, so i do hope i wont be forced to replace them again..
