These boys are capitalists
and they intend to market there product so the wont give there work and
knowledge out for free
flow diagram goes like this signal in from the mass air sensor threw the
micro processor to the ecu
they di say that the increase in air flow with this change alone was equal
to adding 1 pd of boost as in turbo boost
I hope to add one to my daily driver as soon as they start making copys
that's all folks
