335is, DCT, FBO, No meth, Stock inlets. E65 fuel. N20 Tmap. MHD flashed with N20 option checked.. Ambient around 80. Did multiple logs. The first 2 logs were at my secondary log spot. They looked clean. Car felt strong. 3rd log I had the throttle closure preceded by a boost spike. No loss of power during these events. I dont feel any spin. This 3rd log was on my normal road i have done last 150+ logs on. Don't believe the road is the issue as the throttle closure is occurring in the same spot. Seems as though exceeding boost set point/PID at 21.8 psi. Strange because this wasn't an issue with Cobb even in -DA weather.
