It was a V8. And no, it didn't completely survive the trip
As for the M5, the speed limiter delete is usually accompanied by some performance increase. I don't know what exact chip I had back then , since I changed it to a stock chip about a year ago because I didn't want to take chances. My car has been at AC Schnitzer ( so they confirm) but they can't tell what exactly was done. The old suspension ( now replaced ) was ACS and the rims (17's) I bought the car on were ACS too. Furthermore, my car has the AC pump and airpump deleted, but not back then when I set the speed recording.
