I picked up my 8374efr a couple weeks ago! cant wait to get some numbers out of this thing! I do have the internal wastegate but want a divided t4 and will have to go external wastegate at that time. I would be willing to work with you guys because i am burned out on fab work. If you would be willing to help me on a rotated uppipe with no wastegate port and downpipe i will supply the flanges, and 321 stainless from burns stainless! Let me know as i already have one of these it my hands!
