Hey I was looking at the options for dual turbos and I wanted to know if any one had some useful thoughts. Because of price I was looking at a setup from Scheid or Haisley, they look to be about the same but I don't know anything about the S4 turbo. Or if there are any other suggestions. It will be used around the farm for heavy towing and I'd like to pull it a couple times. I can handle up to about 80psi right now but I have a stock 03 turbo.
