Hello. My name is ***** ***** I will be helping you today.

The 266 is usually due to a bad injector. The 2617 is usually a bad cam or crank sensor.

Either could cause your running issues.

Does your scan tool show live data or just codes?

Customer: replied 11 months ago.
Ok, it's actually just the tuner and it only shows me codes

Do you have a multimeter?

Customer: replied 11 months ago.
I do and I have voltage to the VGT
Expert:  Wayne Crawford replied 11 months ago.

Actually a meter wont even be needed. For the 2617 there is a FICM software update that needs done before doing any testing. You will have to take it to a dealer or shop to do that.. I recommend the dealer on reflashing modules.

As far as the other code can you check the compression on cylinder 2?
