[COPOL89]

Joe: The emission delete makes sense, In the engineering department one of there "mottos" was parts not installed have no warranty problems. Also weren't they having problems with the smog pump on some hipo engines over heating the exhaust systems? I could be wrong about the smog pump over heat thing it could have been an isolated thing at the dealership i worked at the time.(or maybe a loophole in the law to remove it) [img]/ubbthreads/images/graemlins/dunno.gif[/img]
