The entire experience was smooth, honest and informative. Tyler gave me extra confidence for the value from the Trans Control Unit flash for my 2015 Golf.:R, three months after getting my Engine Control Unit flashed. He took the time to answer all my questions, and even rode along for a test run to verify my system was running correctly. The investment did NOT disappoint me, and I know I have a tenacious, excellent APR product under the hood. Thank you USP once again for being a leader in this small world of tuner VWs . . . Larry S.
