Dunno what some of you guys are talking about, I called them last week. They took my call and were very helpful. I agree with some of the posts here, You get what you pay for, The EcoBoost can be temperamental at times. I have heard some horror stories of blown motors and all kids of stuff. I took my SHO to LMS for my work they were great and I have had no issues as of yet. They even helped troubleshoot with me when I had issues with my front end (I didn't even buy the H&R springs from them and I installed them myself) But I can only speak for myself. Do your research and like anything else if it sounds too good to be true, that's cuz it is lol.
