I put this thing together about 3.5 years ago before all these issue's started turning up. This was my first experience from a tuning perspective and I must say it's been educational. I've spent probably hundreds of hours on this thing and the past year I'd have to say it's running as well I can make it. Of course, according to all the above information, I'm on borrowed time as I run 20 psi on a TD04....
If I had known then what I know now, I would have had the head work done to avoid the detonation issues..
