The ECU Pro is awesome! After a frustrating month dealing with my car, I had come to the conclusion that it was probaly my DME/ECU. I sent my ECU/CAS and key to The ECU Pro for testing, about 3 days after they recieved my parts The ECU Pro tech had finished testing and repaired my ECU. After I recieved my parts back which was a fairly quick process including shipping time, (expedited option available as well) my car is running perfectly and NO MORE Fault codes! Thank you The ECU Pro. I would definitely recommend your services to others and will use The ECU Pro for all of my future ECU and other modules services.
