Hello
 
	my S Type 2.7 diesel doesn’t like going over 100mph. Not something I make a habit off don’t get me wrong, but owning a power full car and a open motor way I have wanted to try and get a little over 110mph and it has never let me.  
	 
 
	MMA’s soon as I turn the engine on and off the car goes back to normal.  
	 
 
	Any ideas?  
	 
 
	many thanks
