5 Star rating all the way for these guys. First did business with them in 2008 when I brought my new Audi S8 to them for some work and was impressed then. Have been on the East Coast for the past few years and recently returned and brought a couple more of my Audi's to them for various projects, one being the performance chip upgrade for my "NY City Car" an Allroad quattro and again, I walk away totally impressed and fortunate to have connected with a company such as this. Highly recommended for any number of performance products and/or services for your car- They are enthusiasts, and know what they're talking about and care about the quality of their work all the while charging reasonable prices- Definitely a needle in the proverbial haystack in my opinion. If all businesses were like this, we wouldn't need sites like this to report our experiences with businesses because everyone would be happy all the time! OK, so maybe that's an over-simplification, but so many times we take the time to complain about poor service, poor customer service or inferior products, and it is truly refreshing to be able to commend an organization such as this for doing a great job.
