Just installed Kooks headers and cats -tune question

[xgtoblack]

This past Friday I rented a lift in Miami and installed my Kooks headers and cats and used some anti fowlers on the rear o2's and so far no check engine light.. All went well. I currently have for the past 2 years the standard Diablo Sport Trinity 93 tune in and the car runs great. Before the install my NPP exhaust tips got pretty black, now they stay shiny without a speck of soot on them. Does that mean that I'm running too lean? I know that eventually I have to get a real tune either by mail (Diablew)or at a shop. Is it safe to run for a while with what I have ?

Thanks Mike. I have never data logged, but i would need to do for a diablew tune. Is this easy to do menu driven but just plugging into my data port?
