Well since my last post about noise following the install, I now can say that while there is still an on/off chirp/squeal (similar to a belt slipping) at idle up to about 1000 rpm it is running a lot quieter after 450 miles of use

It is truly a different performing car .
An added bonus is the fact that mileage is essentially unchanged on longer trips
