That's good info! I did quite a bit of research and most of what I found pointed to 1250-1300F being the maximum safe EGT for sustained use. That number wasn't specific to IDI or the OM606... but it seemed like safe guidance from a few sources. It would be great to have some good numbers from folks running the 606.
As far as what to do... my feeling is the easiest and most effective solution is meth injection. I think a good intercooler is a good investment but the other approaches (intake/exhaust) I think will offer very modest improvements if any. I have 3" exhaust and given my back pressure readings, I know my turbo's hot side is the bottle neck in my system and know it's too small for my application but I haven't had time to install the larger unit. It will be interesting to see how the larger unit impacts back pressure and EGT.
BTW- my smaller VNT turbo easily produces 25 PSI of boost but that amount of boost (and the added fuel), make the EGT worse- not better. I've turned down my max fueling on the DSL1 since I'm not needing more power but with what I tow, EGT IS my primary concern.

Petar-
