What the hell is going on with shops?

We just took in a 2005 6.0 F-250 that another local Ford dealership quoted $8800.00 for a turbo and 8 injectors and a EGR cooler. When we finished the job for the customer we instaled 2 injectors and a EGR delete kit and cost the customer 1200.00!

How can you compare those 2 jobs ?
1 has a turbo, 8 inj, egr cooler which is more than a egr delete and 2 inj..

I don't see how you can compare when the same wasn't performed.
