This place is legit! Very great customer service and they stand by their work. I had some wiring gremlins after having regulate motor sports install an safc 2 into my supercharged car. After getting it back the car misfired and ran like crap. Drive it down the street into Decatur auto electro before shutting it down because I did not trust the people at regulate to work on my vehicle. These guys did an amazing job in rewriting the tuner for me and even pointed out the crappy job regulate did. They went in and soldered the connections rather than crimping and made sure the job was done right. They did the work at a great price as well and even followed up with me a week later.
