Just want to share my experience with LMS.
I purchased a Cold Air kit and MyCal tuner recently for my 2013 Flex. I ran into a little glitch with the tune files that were sent to me, so I contacted Anthony. He was pleasant, helpful and very responsive and made sure everything was corrected. It wasn't even 30 minutes tops from the time I first emailed him to the point where everything was resolved. My Flex runs AWESOME with the tuner and CAI kit and I couldn't be happier.
I assure anyone reading this, that I have no connection whatsoever to LMS, I am a real customer and my experience is true and genuine, and I would not hesitate to deal with them again.
Well done LMS!!!
