Just try to look up their website. What they offer is nice, but being German it's real pricey. On their 1 tank systems most kits involve replacing injectors, using coolant to heat a fuel plate, processors, etc. I was going to be an installer/ distributor for them but the few customers who were initially interested, changed their mind once they found out how much it would cost. Most people will go for a lower cost 2 tank.
