I just came back from Palm Beach, and thought I would see what the top speed was. Interesting that once it hit 134, the car just stopped pulling. Weird. Anyway, I guess by remapping the ecu, the limiter will be 155 plus??? Anyone top their 550 out and had same results?

I have found out that even if u buy the 63 the limiter is 134. unless you buy the upgrade amg only for the 63 that alows it to go 155. you can get a chip to fix that tho. hehe

Yes. The 1st time I got it up there, I thought something was wrong. After reading a few threads on the site, I quickly found out the best we can do is around 130 - stock. Do a search on gentlemans agreement.
