Hello, do you have the afr /lambda and boost readings from the dyno, in my experience that dyno sheet looks like the ignition is retarded a fair amount. but to make a more educated call the above information would be super helpful
Got any boost numbers? I was thinking either a hose blown off or stuck waste gate?
@ross I dont have those numbers yet but ill see if I can get them this weekend!
@Gord ill check out hoses/WG and let you know
