Well, here's what I've found from research/personal experience. EGT: 1250 is reasonable, but look into an aftermarket intercooler if you don't have one. Trans: 225 seems a little steep. I'd bring it down to about 200-210. Oil: Not sure. Sorry, brother. Boost: Are you running the stock turbo? If so, do you have an aftermarket compressor wheel or any other upgrades for the stock piece? Look into the Overboost Eliminator before you run your boost too high, even with the Diablo tuner. You may experience defueling without it. Then someone might be able to tell you where you can cut your boost off @.
