I have a 2004 Suburban, AWD, 5.3 Flex Fuel eng and was wondering if anyone can expound on the credibility of performance chips to increase Fuel Mileage (i.e. do they work)? Replies to this message: steve_ (Jun 08, 2008 9:47 am) rockman59 (Sep 27, 2009 5:49 pm)

And in many cases the performance chips will void your factory warranty.
