Duane S. Carling CTM Engineering, mustangirs Inferior product AND service, $10,000+ lost! Farmington Utah
Duane S. Carling is a fraud. Too many lies to list. His 'engineering' company consists of only him working part time out of a borrowed garage. (and he's not an engineer either) Don't let the mustangirs.com video fool you! He will encourage you to install it yourself and then ship you unusable components. I paid $10,000 for the kit AND 1500 more for him to install. He delivered my car completely undrivable with a bucket of uninstalled parts, and returned to Utah. Wont respond to me, of course.
