Hello everybody, I have been looking into different tunes for my 2015 Lexus IS350 F Sport AWD. Currently, I have the RR Racing carbon intake with the F-Sport airbox upper and a K&N air filter. Vibrant 1792 resonators paired with the Borla S-Type axleback exhaust. I have looked into the RR Racing tune as there are a lot of videos and posts covering it, but I haven't seen many other tune options. I have also looked into the D3 Performance tune, but I haven't been able to find a whole lot of information on it besides what's listed on their website. Are there any other tune options I should look into? Does anyone have experience with the D3 tune? I'm not looking to install headers or get rid of my cats anytime soon. Any other mods anyone recommends?
