I just got back from the dealer. The other issue I had was the charge of $344.25 for the fuel pump. I checked 2 other local dealers and 3 online sites, the pump was $255 MSRP. Online prices were as low as $180 and all showed MSRP as $255. And they also charged a $49.95 shop fee which also seems high.
So I went in with some documentation and a spreadsheet of my calculated "reasonable" costs and spoke to the service manager's manager. Found out a few things. They do charge $130 and hour for specialty vehicles (Viper, etc.). Originally, I was told a minimum diag charge was $130 but this would be included if they did the work. He worked the numbers and said the labor was only high by about $30 (2.1 x $130 plus $130 diag charge). He said the parts manager set the fuel pump price and there was nothing he could do about that. After a 20 minute discussion, he offered a $30 cash refund or a $236 credit. I took the $236 CREDIT for future work.
Next time I will get the repair details and do the research in advance. I don't mind paying a fair price for service. I just thought $925 (with a 15% off coupon) for a fuel pump and fuel injector cleaning service was a lot. Thanks for the input from everyone.
