More like Mary A+ :) I ordered an engine control module for a Nissan Maxima because FS1 has the best price by far, and they could program the ECM so it would be plug and play. The part was programmed within a few days but the testing took longer than expected due to issues with their testing department. That resulted in the part taking two full weeks to ship which wasn't ideal, but Mary A stayed in contact with me the entire time and provided updates literally every 48 hours. Normally, I would have gotten frustrated, but it was hard to do that because Mary A was so great. I haven't installed the part to know if it works yet, but I have to commend the service Mary provided. She was great. Thanks Mary and FS1!

Be cautious with this company. The 1stpcm I was sent was faulty, never had an issue with my jeep charging until installed the new pcm so I sent it back and called and was told it checked fine that if I wanted another pcm sent it would use up my lifetime warranty so I did and when I installed it I haven't had any issues so I know for sure the 1st pcm wast bad. So I had to use my lifetime warranty for the mistake they made. Be careful buying from this company.

Computer replacement on dodge nitro We had to replace the computer on dodge nitro. Ordering from from here made it so much easier! Everything is done already, we just had to bolt it on.
