A tid but priceier than other euro shops but hands down the best all around in all of South Florida possibly all of Florida. I already had the APR ECU MOD and Forge Diverter Valve little did I know how much of a difference the CAI would make. It's a whole different car. The turbo sounds incredible and drives so smoothly. I'm new to the euro car scene coming from a 99 Acura integra I feel like I'm driving a super car. If you have an Audi, VW, Porshe, etc USP is the only choice. The owner Chris and Mike at the front desk are very informative and on top of their stuff. Very educated. I will not let anyone else touch my VW as long as I have it. Thank you USP can't wait for stage 2 upgrade.
