Did you measure the a/f ratio at the tailpipe or the bung that was installed last year? If it the tailpipe, the cat has an effect plus there is a delay in the reading. Also, what type of O2 sensor was used? Was it a wideband sensor like I use or the type used by emisions testing places where the exhuast is sampled by a hose?
I finally have time to look at the tuning I read from your car, I'll have a look to see if I can lean it out.
