Ok I have 2013 with paxton via beefcake and finishline tunning, install and purchase was great experience. Terry and Brian are great guys and an awesome combo vendor and installer wouldn't hesitate to recommend. Now with Lund they did my dyno tune and I was tuned by Shaun/AED before and had great experience I would have him tune it but Terry was dynoing it and he has great relationship with Lund and we were on limited time. I've read about Lund and there customer service was questioned but I'm here to tell you they have been ultra responsive and returned service tickets with in 10 minutes two times and one was done at 9:30 PM. My tune is spot on but I'm using meth and wasn't tuned on purpose using it as a safety but it is affecting my AFR so I wanted to see if they could do something about it. Which they did but they read my datalogs and wanted to address something to make it better not that I had a problem but hell yeah. Great tuner! service on par with AED, Shaun is also a great tuner as well!
