Its an odd problem? not sure if it is a problem, but could be. Even when I cruise and reading lean, people behind me say It smells like fule and really rich. All AFR's are reading fine so not sure.

It i a AEM uego about 4 feet maybe less after the turbine housing in the test pipe mounted at a 45* angle.

Any ideas what could be making it read lean if it is really rich?
I am running nismotronic, I have been working with John to get it running well enough to drive it to him to tune it. Just making sure this is not something bigger than just tune. Car drives well regardless the lean/rich issue.
