Hey Im just starting to dig into this RX7 performance upgrade stuff and was wondering what are the effects of taking the EGR valve right off? I heard that it would increase emissions(who cares?) , increase power, and increase fuel consumption. The latter being caused by the ECM going into an error code state and running rich. If I got a chip that would negate any info to and from the EGR valve(do they exist?) would there be any other concerns??

Is there anything to worry about doing this??
