Volvo D16 Injector question

Having a similar injector issue. I have a 2011 D16 deleted with 600 tune truck was running great then all the sudden started missing got off the road and parked engine was shaking pretty bad so I shut it down. Code Sid 5 fmi 7 for #5 injector replaced injector but the shop did not have tech tool to program still showing code and idling rough they just said well it's deleted and washed their hands of it they did inspect the harness and couldn't find anything. After I picked the truck up I checked the harness plugs on the side of the engine and found alot of oil from the shop working on it so I cleaned the connections and blew them out with a can of duster no change.
