2004 Chevy Burb 5.3L

Reviewed By Lawrence M (Stratford, CT) Reviewed for a 2004 Chevy Suburban —8/5/2011 5:04 PM

Added a Spectre intake last yr. A bit noisy when you push the pedal. This yr bought the programmer. Seems to have more power towing the trailer. Shifts are fast at 75%, 300 rpm higher setting and regular gas. We also added 2 9.5 foot kayaks(more wind resistance)to the suburban roof. mileage on the first 180 miles was about 9.2 mpg towing hills going up rt 8 in CT to Schenectady,NY 0n I90. Truck runs smoother and the shift points are perfect for towing a heavy trailer. Mild grades were towed comfortably with a noticible improvement in performance. Steeper hills were more of a challenge, but still impressive. On the way home to CT got 9.5 mpg.

Easy to install. Noticed increased power right away. Acceleration and shift points are great. Haven't switched program to tow mode yet.
