i use nothing but 205 in all my cars
xxxt-cr with 6.5 v3
xxx-cr with 8.5 v3
xxx-sct with 7.5 v3
custom built sprint car with 7.5 v2

i have an extra speedo that i use to test all the software updates
but the boost software just never feels right for me..as our track has like 60ft straight and it seems to always come on too late for my taste

we do have a large outdoor offroad that im going to load the newest SW in and go play.....so my feelings may change on booooooooooooost
