Alright I have a bolt on only 60k mile 95 Z28. Pacesetter race LT's ORY !EGR !AIR Magnaflow catback and a CAI. Since I did the LT's and deleted the emissions system I've been having Air/Fuel problems mainly was running rich down low and lean past 3500rpm. I hooked up tuner c.a.t.s and used TSS datamaster to monitor everything after deleting the codes for the emissions and adjusting fuel trim levels. Car runs great around 14:1 up until 3500rpm now but, still seems to be not getting enough gas past 3500. But to get a more accurate reading and keep track of it instead of relying on the o2's and datamaster, I want to get a decent wideband gauge to monitor. I can get a pretty good deal from a friend on a used NGK Powerdex AFX Air-Fuel Ratio monitoring kit (http://www.extremepsi.com/store/customer/product.php?productid=19563&cat=1089&page=1). I know its not a "gauge" but I think an LCD display would be good for me. Anyone running one of these? I'm new to this EFI technology so just wondering what you guys think about this kit and would you recommend buying a slightly used one and saving about $100? NGK seems like it would be a pretty reputable name for anything to do with fuel/ignition. Thanks. :D
