2017 RAM 2500 6.7liter OEM turbo failure at less than 100K…read moreWe brought our 2500 because of an "Turbo Actuator beyond learned limits" code. Eddie took it in and Nate analyzed the problem to find the turbo itself was failing (common for OEM Holsets). Nate recommended an upgraded turbo and Eddie suggested a BD Screamer to maintain Ca compliance. Due to great Dodge engineering the headgasket failed so we upgraded to a Mahle headgasket and ARP Headstuds. Both Eddie and Nate are extremely knowledgeable about turbo diesels! They are the Diesel Doctors! I trust their recommendations and their work was top notch! They went the extra mile in areas to make the repair job last for the long haul. Nate also told us future steps we could take to lengthen the lifespan of the 68RFE transmission (they all fail) and future upgrades. WHEN your RAM wants to see the doctor (they all will) bring it to Fast Eddie. He and Nate will get you back up and running! Eddie and Nate were so willing to talk to my wife and I keeping us in the loop along the whole process - trust earned! What are you waiting for? Fast Eddies is the place - stop hesitating. Tow your diesel in if you have to!

Eddie is the man with the plan. Straight forward with quality service. Best in the area.read more

I just purchased a new battery from them. The employee told me that it might be your alternator? Today, I brought my car in to have my alternator replaced. Speaking with the owner, He told me the issue isn't with the battery or alternator. It's with my aftermarket car alarm. For some reason, it is draining my battery. The moral of the story is being honest will pay off. I will definitely return and tell all my family and friends. Thank you!

Quick and honest service!…read more I sent a message on Yelp requesting a quote for an oil change. They responded very quickly, priced fairly, and even provided time slots they had open, so I headed to the shop that same Saturday. When I arrived, they quickly directed me to pull in to start the service. It seems like I had just sat down when they called me back out to show me the the underside of the van. They wanted to know where I'd done the prior oil changes since whoever did them had stripped the tread on the pan from tightening the bolt too tight. I could clearly see that what they were saying was true and the pan had no tread and had been leaking oil this whole time. There really would be no way to do the oil change without also changing the pan. I asked how much that replacement would cost, and told them to go ahead complete the repair along with the oil change. This is my mom's mini van that I was going to drive back down to LA, so definitely wanted to ensure I was safe. I was told it would take 2-3 hours, but was quickly out in about 1.5. They even provided a discount when I paid since the repair was unexpected and fast, which I really appreciate. They pointed out some other concerns, but did not force any repairs on me, which I am grateful for. Will definitely be coming back for any future oil changes and repairs.
