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.

Reviewed By Tim D (loganville, GA) Reviewed for a 2003 Chevy Suburban —2/16/2016 3:36 AM

Works great. Monitors trans temp and other useful things using the xgauge feature. Plug and play for the most part. Needs calibration to give you accurate fuel readings.
