I can tell you that I have no affiliation with LET/Eurocharged, but have had their tune and products for a couple years now. I am in California and they are in Chicago. I've also been following them on both forums and had them help me personally as well.

Jerry, Tony, Jake, all stand up guys that aren't just here to make a buck, they're passionate about tuning these cars. They also started out as regular members and then started a business cause they enjoyed it so much. They won't LET you down and if you need something, they will always be there for you.

Besides the fact that they have great, time proven products and tunes, I can give them my highest recommendation.
