ran instant green DYO a couple weeks ago , 0.400 tree here in Oz for all racing
2 things I see ,
1 it takes delay box out of the equation . We were mixed box/no box
2 lighter / faster cars have a bigger advantage . Hard to get my near 3800 lb Satellite going from 2000 when footbraking .
Pro tree DYO is a bit better with 1 warning light
