05 ISX 565 Surge, loss of power, ideas?

I’m for sure not driving it, will swing by shop tomorrow and discuss with them, this engine and program had been done several years (3+ years OTR), had no problems with it until this last 6 months. It has been a great truck otherwise.


Regarding the turbo, when we called the dealer they told us the cummins rebuild or quality equal was on national backorder but they offered us the D&W which was in their words a solid alternative.
