Question,the previous owner of this 87 Turbo T had 3 chips. A thrasher 92,one labeled "race 116" assuming that refers to race gas, and then one that says emissions. By emissions does that mean this is the stock chip, or is it a chip that greatly reduces C0,Nox readings by running the car super lean or alter it some other way to blow clean on the machine. I drove the car home with the thrasher in it and it runs strong with red stripes and 45psi fuel vac off. Just curious one day popped in the emissions chip and car is definatley slower and smells really rich,it also turns on the check engine light on after boosting it. Should I be driving with this thing at all or should I turn down fuel pressure to match it if it is a stock chip?
