So I was cleaning and finding more things with this car. Im not exactlay sure what stage this car is but heres what I found, Downpipes, Full exhaust, High Flow Magnaflow Cats, Intake ( Ithink?)HKS BOV's and came across an JWT Chip Inside the ECU. I think the guy who had this before had a field day on the concept Z performance website. lol
Changed the O2 sensors with Bosch and hooked up the AFR gauge, now im getting about 25mpg highway
but I failed smog for NOx readings, so gotta check the EGR system, more than likely Im going to have to replace the valve, which doesnt matter to much to me because I have to get to the knock sensor anyway so that can be changed at the same time. Also I have a blown rear driver strut so my car likes to YAW on the freeway over aggressive bumps, not too bad in the dry but heart stopping in the wet. 
still... for $3000 I really cant complain I still got alot of car, but shes got a long way to go before she will be damn near perfect.BTW anyone know how to mess with the Greddy turbo timers? I cant get mine to work for some reason...
