The same procedure on the N54 works amazingly well on our N55's. I reversed the spring position and viola average operating temps 200 degrees. Running hard is about 215. Car is running at its max performance, no timing pulled due to heat. Very pleased with the mod. I let the car get to about 180 before dipping into boost to avoid oil starvation. Takes a little bit longer to warm up, but I live in California so no worries here.
