I've been looking at putting a chip into my trucks ECM to gain a little more power and better gas millage. How hard would it be to put it in? I know you have to take your ECM out and put the new P-ROM chip in. Where could I get the right one and is it a difficult job to do? I only saw a stage 1 chip on eBay that was listed for about $150. The link is below, would that be one that would work with my truck? 1995 C1500 4.3L Manual trans. 5spd. JET TBI Spacer Upgraded plug wires Stage 1 Chip: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330503311443&category=33597&_trksid=p5197.c0.m619 Thanks for your help all!
