If you are making 9psi at cruise, the vane position is way too tight and that will cause high EGT in itself from high DP.

| Yes, too much boost for sure. And I would think you were told the wrong size of the injectors... If He's tuning for what you were told, and they are bigger your going to dump more fuel than you think. Raising EGT's.

| Oh, I didn't know if you bought the motor with the injectors already in it, and were just told they were 30 overs. I was just trying to think of what it could be... Those EGT's are crazy high. FYI I used to run EDGE Juice with Attitude as a tuner. They are a REAL professional company that sell Thousands of units. But when I had that tuning I was getting high EGT's. Hitting 1400-1500 easy. But when I switched my tuning to ROB CODDENS the EGT's dropped drastically. I couldnt get them above 1350. This is just an example of the difference between 2 "Professional Tuners". Something to consider.

| The OP already has this question posted in the EFIlive section: http://www.duramaxforum.com/forum/ef...ml#post1876214 Boost IS NOT fine.... it's listed as 9psi at cruise there. No timing #s have been given. .
