Yep lms is correct. T7 is wayyy too sensitive for any kind of atmospheric dump valve. T5 was a map sensor, so dumping before the TB made no difference - not so in a MAF/AMM car like your viggen. Stock valve can handle ~20psi. If you want a little more noise/engine bling, get the Forge recirc valve. Nice thing is it's all aluminum and completely rebuildable.
Also, some have said certain 3" downpipe designs cause the o2 fault code. I have a JSP 3" w/3" magnaflow cat and have no code, but YMMV.
