Tune 2008 Lexus IS 350 OBD ECU Upgrade Tune January 20, 2025 Reviewer: Nicole Brown from Flower Mound, TX United States   Purchased for our 17 year old for Christmas. He found it easy and straight forward to use. Quick turnaround time for the tune file, even on a holiday. Ordering process was also easy for me. Timely shipping. Even at my age I can hear the performance difference. RR Racing knows what they are doing and doing it right. Was this review helpful to you?
