A discussion on EGT and Exhaust back pressure on an OM606
I re-checked my vacuum control converted GTA2359VK stop setting today and it produces about 1250 mb at 2000 RPM full vacuum in park. I think still good. I also straight piped the truck today and wow what a difference! Everything came to life. EGT's dropped tp 1200f max and the truck accelerates unbelievably hard. The turbo easily hits (and exceeds) the current 2500 mb max boost in the tune. Plenty for the stock IP and good fuel mileage. I'm gonna have to start all over with my tune from Baldurs' basic vgt tune. I'll start with decreasing duty cycles throughout as the boost swings a bit wildly. Shout out to Zeeman so I'll probably invest in the Spintech diesel muffler as the highway drone is annoying straight piped. The Flowmaster muffler I had on it is going into the scrap heap. At this point, I don't see any need for water/methanol system.
