I just installed LTs on an otherwise stock engine. My A/F, prior to the LTs, with cats, reading from the tailpipe was 13.8.
Now, with the headers and my AEM wideband, I am reading anywhere from 14.5-15.5. I thought the A/F would go the OTHER way after headers!
Kinda worried about this. What do yall think?
Im wonderin if it will just take some time for the ECM to relearn the perameters, because my guage is really everywhere.
