i installed one last month. It works killer. I put it on a 215 pump with a 10 plate and slide the plate full forward. Full forward the truck would smoke like a mad dog even with the boost maxing out the 50 lbs boost gauge and a B-1. So i put the afc controller (which gives u the ability to limit rack travel in the cab) so my custumer could have full fuel when racing or limit the afc travel to make it easy to drive and less smoke. I works great, but they really need to offer a longer cable with the unit. Let me know if u want one.
