Received the package in 5 days. Installed in less then 5 min on a Skoda Octavia 2019 and it`s a clear difference in acceleration and power. Good customer support! I recommend this guys!!!
Fast delivery, had an initial issue with one of the connections, but 1 phone call and a technical email later all resolved., I have tried racechip previously but I am more impressed with this company.
My dad wanted it so I ordered from Japan. My dad told me that it works perfect and highly recommended. We live in Japan and have Range Rover Velar. Dad said it takes about only 3 mins.
