My buddy sold his 06 and is selling his bully dog triple dog gt. I have a 2007 5.9 with the g56. The truck is bone stock except for exhaust and intake. I'd like efi live but dont really want to shovel out the cash on a marine corps paycheck. So just wondering if I should give it a shot, he only wants $300 for it. Not looking for crazy power, just a little more "umph", mpg's, and monitoring. So any input would be appreciated
