gotta interesting issue here...
i had my car dyno tuned last fall (Dez Racing in seekonk mass)made a bunch of timing + fuel trim changes....
now i go for my annual state inspection... no go

.
state says "catalyst monitor +catalyst heater mointor not supported"...
but car has BBK cats + o2 sensors, never had my check engine light go on...
so here's my question... the car was tuned with an older predator..if i suck the perfomance tune out, put the "stock" tune back in , get a sticker, and then re-install the performance tune.. will i loose any of the fuel mixture + timimg settings, or does the predator retain that stuff?
