Blown mach air fuel reading
Hi all!
I have my procharger mach 1 and Have some concerns regarding the air fuel wide band reading. I only have one sensor on at the minute. Ideally I should have two right? One each side coming out the engine? At idle, I am seeing 14.7 to 15.3 average which I guess is ok. However under WOT I would expect to see high 11s or low 12s but it barley breaks 13s and some times flickers up to 16 and 17. I am running aereoforce interceptors. This can't be right? This must be running too lean? I have to normal tune procharger sent. Thanks, Dean

Re: Blown mach air fuel reading
13 is too lean for a blown car. If it's showing 16-17 then you have a time bomb.
