This tune helped me to achieve my goal. i don't like Time Trials so I don't put in very many laps. I shaved almost 1.5 sec. off my original time in just 2 laps. It was a tad bit loose for my driving style but by the 2nd lap I had achieved my goal. So I would recommend this tune as a base point. My vehicle weight was lighter but the tune for the suspension was just right. I did use my own tune for the gears since I run M/T,
