Actuator failure being caused by bad de-mandate tune?

[BRUDER01]

Similar story to many- De-Mandated my 600 ISX last summer using a “reputable” tuning outfit that quite a few other guys in my area had seemed to have decent luck with. Did the physical re/re of filters myself, no cutting or removal of any sensors or harness components.

Fast forward a few months- Turbo and actuator are toast. Replaced- actuator lasts a couple more weeks- fails/ figured it was faulty, installed new one under warranty. Now a couple months latter it fails once again. The more time I spend researching and reading on the site I’m starting to see the trend that it’s more than likely being caused by a poor tune-

Now before I go throw more parts at this thing I would like to find someone who is experienced and willing to have a look at my file and hopefully point me in the direction of someone who can straighten out my tuning problems should that be the issue.

Thanks for any input in advance.
