I was searching more reliability on stock form than performance actually after my bad experiences with MP boxes. And honestly I didn't get dissapointed about.

Aside that, got a smooth ride and good performing, Fast start up, ( not faster than a chromed box thought ). I'm using the vacuum. Having pinging BUT is not related to the Vacuum, since I have disconnected the vacuum and still the same, so will be plugged again, althought limited to 4 to 6 degrees ( adjusting the internal screw ). Is not a race car even being a stroked engine.

The unit I got cames from the first batch ( 00020 S/N ) and on a release offer ( $120 or so ), no tach lead or any later upgrade. Simply got satisfied with what I was searching for and what I paid after 3 MP chromed failed units ( $210 in total ).
