2014 BMW 535i (N55) in the shop for an intermittent stalling concern.
This Stage 2 full bolt-on build is getting a complete diagnostic—not just a code scan. We'll be analyzing live data, fuel system, air system, and engine parameters to pinpoint the root cause. If needed, we'll verify the repair with live data under load on the dyno.
At Xtremity Performance Garage, we don't guess—we diagnose. 🔧💻🏁
