2014 Lexus IS250 Tune December 26, 2023 Reviewer: Tysyn Rolle from Houston, TX United States   This is probably the best performance upgrade and overall value for any Lexus IS250.  With a good cold air intake, free flowing exhaust system, and Apexi Smart Accel throttle controller, adding the RR Racing tune made my 2014 Lexus IS250 perform like a totally different vehicle.  I’m able to compete in acceleration with vehicles that have significantly higher horsepower ratings.  The tune is a must have for anyone who wants more power and acceleration from their IS250 without losing reliability and fuel economy.

Great tune made all around driving so much better July 31, 2023 Reviewer: Justin O'Donnell from Cornelius, NC United States   I got it and some other performance items as in intake and injectors.  The tune let it all work together and perform better. Only thing is once I got my tune I’ve tried reaching out to RR racing for some questions but am getting nothing back. Was this review helpful to you?

Smooth Power Curve & Shift Points April 29, 2023 Reviewer: Jetson Chong from Edmonton, AB Canada   All of the Lexus IS250s should have came like this stock to begin with! I drive a 3rd gen IS and all I can say is this is a great tune for such smoother shift points and way easier time getting up to speed in the top end of the power curve! Hit 170kmh (105mph) a lot quicker than stock! Great tune! Also noticed driving normally seems to be a lot smoother with the shifts, and the throttle response is a lot more lively.
