Datalog review

[RedGT45]

I recently purchased a tune and was wondering if somebody knowledgeable could give me a second opinion on my datalogs? The tuner is helping me out but their communication has been a bit lacking. I don't want to call them out or anything because Im not angry or anything, I just want to get a better idea of what is going on with my car.

Just to give an example of something I see wrong, lambse will show .65 when measured AFR is at .99 at mid rpm WOT. Are they calling for it to run rich and it is actually running lean?

I will give more detail in an email if somebody is willing to help me out.

Post up your datalog

It doesnt matter what they are "calling" for it to do. If you have a vaccum leak and unmetered air is making it into the combustion, you will see what you are seeing.

No vacuum leaks, it was all in the tuning. We got it sorted now.
