Hi there. I have an 04 that I installed a SC on a while back. I was wondering what you think of E85 and if you have ever tried it in your truck? Rob Williams of RWR Motorsports has done my tuning out here in the Denver metro. He has a great working relationship with Troyer and has taken tuning classes from him. He thinks that we might get lucky and my fuel system can do it. We are going to have my truck on his dynojet anyway so he will test the system. I am not getting my hopes up but if I can run it I would like to do it.
