E90 320d performance drop off after remap....
Had my car remapped and for the first few days it really did fly..!!! It was as quick as my mate 3ltr Z4 upto silly speeds.
After a few weeks the car doesnt see to have the same performance, yes im sure you get used to the performance but my mates Z4 does pull away now when it never used to. I have always used BP ultimate / shell and never put supermarket fuel.
Its still a lot better than std still but not as quick as when it was first done. I think.....
Anyone had similar experiences ? May get it rr'd.
