I just want to give a big shout out to Revan Racinig, I can’t remember the persons name I talked to on the phone though. I wanted to share my experience with him, I called inquiring about a HE for my 14 Shelby, was ready to make a purchase today. The gentleman asked what all I had done to my car and what I was trying to accomplish by this HE so I told him that when it is humid out the car loses power like most boosted car do. After talking to him for a few he explained that a tune would help my issue more than an HE upgrade he said the factory HE on the 13/14’s are really good. Long story short he could have sold me a part that I didn’t need and I wouldn’t know any difference. I just want to say thanks to Revan and the GT500 forum.
