I'm running around 1:48's at Vallelunga with the Alfa 155 Ti V6 with stock setup. I'm running final ratio of 9//49. I'm also working on Mercedes Benz 190E 2.5-16 EVO II. I'm using gear set 2 and final 10//43. I don't understand the other settings for setups very well. I know there is a way to improve by a few seconds, I just don't know how to get there.
