While I like the idea of possibly being able to run CNG, I am in need of a vehicle with power that can tow heavy loads. Currently, my Chevy Duramax has 500hp/745ft lbs of torque with my Edge system. I am wondering if CNG can give me the same results, if it is even possible to run a diesel engine on CNG. I know that I can instal LP injection (similar response as nitrous to a gas engine). If it can't run on CNG, then it is useless to my needs. I think this is the largest problem for most Americans. We love our power. I don't just need it for a hot rod. I have a couple of trailers that I pull for my construction business that weigh 10,000 and nearly 20,000 pounds.
