MY VEHICLE (2009 CHEVY SUBURBAN) HAS OVER 100000 MILES. WHEN I FIRST DROVE IT AFTER INSTALLING THE 71 SERIES SYSTEM I COULD EXPERIENCE THE CHANGE IN EXCELLERATION AND ON THE HIGHWAY A TRUE GAIN IN MPG. I NOTICED THOUGH THAT IF I PUNCH IT WHILE GOING ABOUT 50 OR 60 MPH IT SEEMS TO BOGG DOWN A BIT. OVERALL I AM TRULY SATICFIED WITH IT,LOOKS TIGHT UNDER THE HOOD ALSO
