WOW, all I have to say is wow.

Just used this on a 60K mile 2014 Jetta 1.8L SE TDI engine. The car was running great, fuel mileage was very good at ~40 on the highway. Followed the direction, got the engine hot, emptied can into intake, shutdown and soaked for an hour. Started the car and drove it like I stole it. WHAT a difference. Better throttle response, quicker spool up and 3 more MPG according to the computer. Also noticed the engine seems quieter.
