Several good sources of information here. If you ordered the Denmah kit then it comes with a wastegate. That is the part in the system that controls boost. Without it a gas V8 has enough BTU energy to spin a very large turbo really hard (POOF!). The turbo will not self regulate like they do on older diesel engines. I see the Missouri (misery??) license plate on the car, is that where you live? My parents live there and i wish i had access to E85 like they do. Build your fuel system to use it as it is very forgiving of tuning issues unlike pump gas, especially timing mistakes, ask me how i know....
