I had a REVO chip on my Tiguan from MJM and I loved it. It took no time to load and the power/gas mileage I got was well worth the price.
Glad to hear the Revo Technik Performance Software is doing its job in the Tiguan, SooprmanX. Oh, and be sure to let all your buddies know that MJM Autohaus, in partnership with famed custom show car body shop Garage Arte, will be opening a Houston location (in the Willowbrook/1960 area) and offering in-house Revo tunes there, too. We're stoked about it. Stay tuned to the forums for more info.
