I wasn't aware that they were restricted..... :confused:

I guess he means the top speed limiter? You need the ECU re-flashing.

Hi,yes your right its limited to 155, how do i get the ecu done? thanks

[Greengoblin]

I've heard that it's actually 161mph on the S4, dunno if this is true or not, but I can confirm that in a "controlled situation where its legal to do so" you can fill the clock............. :D

Of course the previous owner could have removed the limiter on my one. :confused:

[BoyceyS4]

Yes it is limited to 155mph, would like to see how fast this would do?

I could do this for you if you require it.
