Testing with JB stage 1
Finally return my car to stock mode and was able to do some baseline testing. Got 0-60 in 5.5 in stock and 5.2 with JB. I thought BMW claims that 5.2 can be achieved with stock car and most magazines are testing to be around 5 seconds? I would expect at least 5 sec with JB. Did my car just happen to be slow?
