    Hi All, Just got my EGR deleted and engine remap done on my Range Rover Sport 3.6 V8 TD, and all I can say is WOW. What a transformation! The tank had power but there was a delay before but not anymore. Also I was getting the EGR fault coming up in the last month and the guys at STX have addressed this problem once and for all. Thank you to all at STX, I will definitely be recommending their services and will see you again as I will be bringing the tank to you for all future servicing requirements! Thanks again! Naz
