Thanks. Do you have a chart or printout of the runs with an AFR log for the headers? I'd like to see if it leaned out in the midrange, or if the DME was able to accommodate the the change in flow if any.

You are really making me work, not that I mind.
Nice to get some good questions. Rob at S Car Go is going to send them over to me. As soon as I get them I will post. He said the AFR's run from 12.1 to 13.3. It hits 13.3 at aprox. 7600 rpm's.

Steve,
I just noticed the AFR's are on the last chart I posted on page two.
It's the black line, On the bottom of page it give high, low and average also.

Right, that's the afr chart for the stock exhaust. It would be good to see how it compares to the chart for the headers to see if there was any change. Sometimes the Motronic systems can accommodate to changes in engine flow because the HFM sensor voltage rises with the flow increase, and a lot of times if the change is a bit too much that only a remap can correct.
