Wright-Patterson Air Force Base to be exact. I've been in a little over 10 years doing a wide variety of career fields...logistics, security police and information management. I have a black 2001 K1500 V8 5.3L Suburban LT with Goodyear Fortera with Silent Armor tires. I don't know too much about trucks yet, but will be looking to make some upgrades soon. Right now all I have is a K&N air filter. I'm looking to put in a CAI, an instrument cluster replacement and do some retuning. I found a Trip Dog Downloader on stylintrucks.com (http://www.stylintrucks.com/parts.a...anned_results_trigger=&selected_prod_ids=5821) What do you guys think??? Is there another good tuner that's cheaper that you know of? Thanks for the help!
