Yes, I've test driven other M5 and the "butt dyno" reads that they are stronger. Does anybody know how "accurate" is the WOT to 7k RPM test. Does it always suppose to read 140 L/H at 7K? I told Active about this "test" and they assure me that test No. 4 on the "Test Menu" from the dash is nothing more than the data that the car uses to compute the MPG average. obviously it makes sense the computer would use such date to compute the MPG, but I think that he is missing the bigger point that it may have to do with fuel delivery and ultimately the AIR/FUEL mixture. If this "test" to 7k rpms holds water, then it means that there is something wrong and I just have to keep digging deeper to find the problem. Otherwise, what Active is saying is true and it makes no point for me to have them keep running tests on the car, to simply find out that the car IS running fine and I am simply chasing my own tail. What do you guys think?
Does it truly mean that I have a problem with my car if the WOT test with engine warm in Test No 04 is reading only 90 -95 L/H at 7k RPM ???
Thanks in advance.
