ugg greddy blue box


if you don't want your car to blow up you need to get your ecu chipped and run uberdata (cheap) get rid of that greddy blue box and GET YOUR CAR TUNED, it would help if you upgraded the injectors and maybe the fuel pump. As for other guages i would recommend oil psi, boost and egt guage (expensive used to not melt engine) but the only main important one i would say would be boost because if that goes too high, your done. as for what is wrong with your car, it sounds like you need to talk to a pro about that one
