Yes, I do believe that I overheard Jon speaking with Gary at
the end of last week regarding an ///M2. You're in good hands
with the team at GRATR, and we'll keep an eye out for your
review / feedback after the install.

I have a good feeling we'll be adding another happy customer
to the list...(in good company with some of the others in Post #486)

It sounds like I need to give VF a call.
My 15' M235i does the same thing, it violently lurches above 6k. I am running the Dinan IC, CAI, Berger Mtrsprt CP, VRSF catted DP and VF's Stage 2 tune. I always run 92 Octane gas and do not at present have any power adders , but was eventually going to go with W/M injection.
Glad to hear I am not the only one, I was thinking "Great how much is this going to cost me?"

I spoke with a guy at VF and I told him that I was getting an engine code 11801. When he first looked into it he told me that the specific code of 11801 did not exist and all the codes are usually only four numbers beginning with a P designation.
But after some deeper investigation he did find out that the code of 11801 did exist and it specifically named cylinder #2 as incomplete firing, duration of firing too short, etc.
So after that I went out and bought a set of Bosch replacement coils for the car and after installation that took care of the problem.
