I always also bill to reseal each injector and check the cups for cracks and the correct torque. Valve cover is off anyways its less than 1 hour per side to do them all once your in there and the seal kits are 8 bucks each. Ids has a great power balance. You should know if it has a bad injector or not. Check it cold and bump the rpm down to 500. I use ae and it is way more work. I also always charge to inspect and reseal the egr valve if equipped. If you opened the oil cooler and got any contamination in there the ipr screen could have taken a hit as well. I would check that but if it has 500 psi or more it should be fine. Did you do the screen while the turbo was off? It's another cheep insurance.
