Wow I don't know what to say there are so many things that scare me. First of all unplugging waste gates is a good way to buy new engine, secondly if you never had BOVs before there is a lot of fine tuning to work properly and your EVC has to have warning values set cuz out of box set at zero which means little or no boost. Codes 34? Safety boost. Slow down and search Dyno day. Piss poor preparation equals piss poor performance. Not being a smart ass but patience is a needed trait owning a Z. Good luck
