Hi All,
This is my first post on your very cool site!
I have a LEASED 08' Range Rover Sport and I'm looking for a performance program or chip to add horse power.

I had an 03' GMC Yukon that had the PCM programmed by Westers Garage. Their program gave me a 50 hp gain! Thats not a typo. It was awsome!

Westers doesnt have anything for the RRS so I came to the experts here.

Is there anything out there to squeeze out more horsepower without a supercharger or other drastic mods?

Remember, Its a lease.

Thanks!
