Power tuning the SC430, Wideband and Neo

After all of the mods on the car I put on a NGK Powerdex AFX wideband O2 sensor to monitor the a/f ratio and to my pleasant surprise the car appears to be running a bit lean at low rpms. I say pleasant as I should be able to tune in some additional horsepower here.
So I picked up an Apexi Neo a/f computer as pictured. I will update as I go along but hopefully I will get in some decent settings before taking off the meet this weekend. Install of both units was very straight forward though I wish the Neo had about an extra 3' to the wiring.
Not exactly cheap as the O2 Wideband was $245 and the Neo ran me $295.00 but like they say about paying and playing.
