First off you can read about the majority of my experience here: http://www.stangnet.com/mustang-for...t-my-feelings-about-them.660098/#post-6403699 Now, 7 years later I'm paying for their f*ck ups again. I recently went in for Salt Lake County emissions testing. You can read about that here: http://www.stangnet.com/mustang-forums/threads/fml.870915/ They lied about my stock parts. In all fairness, I was really stupid and naive to believe them and leave the parts with them. I was just young and dumb. But the STB was a crock. Now, 7 years later, I find out that when they tuned my car, they disabled emission systems monitoring AND engine misfire monitoring in my ECU. I'm pretty sure that is not standard practice for most tuning shops. Now I have to have a dealership flash my ECU to get it to monitor those systems again and then re-tune my car with a mail-order tune. After seeing what MD was all about, I'll probably see an improvement with my handheld tuner...it wouldn't surprise me. Conclusion. F*ck Modular Depot. I know they moved or merged with some other shop in KY. Hopefully no one associated with the old MD is still there. If so, do yourselves a favor and stay away.
