So I raced my friend who has a 2006 lly with the ppe programmer on the 225 setting, his truck is lifted on 35s and I was on the 5th trans safe efi tune.. Around 100 horse, and I was shocked when my truck beat his as we got on it from about 60mph on the highway, I simply just pulled away from him. Off the line he took me though, just more praise for efilive tuning fellas!!
