Tune July 31, 2024 Reviewer: E from Brockport, NY United States   Customer service was good and quick to respond with tune but advertisement is not accurate it said would increase hp by 50-60 with headers and about 20-30 without headers after doing dyno found I only got a 10-15 gain in hp don’t get me wrong wasn’t expecting crazy gains but for the price of the tune was expecting a little more gain than that Was this review helpful to you?

Great tune! Worth the money June 4, 2024 Reviewer: John Dang from Lawrence, KS United States   Had my 2015 RC 350 AWD for about maybe 2 years now and loved the car. Had an intake and exhaust installed prior to the tune and thought it was great, but when I decided to get a tune oh my goodness it made the car feel so alive. The biggest difference was the throttle response. The moment I started the car and drove it around, it was crazy how much delay it had prior to the tune. I even let my friend with an RC 350 drive it and he noticed it immediately. As well as the increased rev limit. It made the car feel so alive and amazing. 100% recommend the tune to anyone who wants to improve the RC performance and feel. Was this review helpful to you?

Amazing honestly May 19, 2024 Reviewer: Anonymous Person   Easy to install, had the carbon intake and k&n filters along with the tune; made a huge difference in performance (throttle response, revs to 7200) in the car, thoroughly love getting in my car now post-tune. Overall, just simply amazing. I am a lifelong customer now! Was this review helpful to you?

2016 IS300 January 18, 2024 Reviewer: Sebastian Bres from Perrysburg, OH United States   Purchased the tune on a Saturday, and received the tune file back on Tuesday. The process is very simple, just follow the instructions. There's definitely a noticeable difference with the IS300, totally worth it if you want it a little faster. No hit on gas mileage either.

Strongly Recommend March 8, 2023 Reviewer: Matthias Despeignes from Taunton, MA United States   Feels like a whole different car after the tune! If you have an exhaust and an intake, it will sound much better! Was this review helpful to you?
