Please note that you can also buy tune and headers by selecting the headers option when buying the tune product. Also you can buy an exhaust with the 3XX tune (please select the tune as an option with one of the exhaust products we offer). The tune that comes with this product is for the following models with 2GR-FSE 3.5L v6 engine: IS350, IS300 AWD 2014 and newer (3rd generation) models.RR Racing is proud to release yet another great value performance package for the Lexus! The Lexus 300/350 ECU is a very complex and sophisticated engine management system. As always, we have worked very hard over a course of many months on developing this tune using our IS350 F Sport shop car as well as our customers' cars. We developed both on the dyno AND on the road. We have thoroughly tested various changes in order to optimize power and torque effectively while retaining stock fuel efficiency, knock control sensitivity, and other built in safety features. We especially excited to report the results of our IS300 tune. Now IS/RC300 owners can have all the power of an IS/RC350 at a fraction of the cost, by simply recalibrating the ECU! So as you can see this was not a weekend project for us, where we slapped a Lexus on the dyno, played around a bit for a day or weekend, and and now we are selling a tune. We had done most of our development on the road, under real world conditions, doing hundreds of runs, datalogs, and hundreds of miles of testing between re-maps in order to determine how the ECU reacts to changes and adjust learning parameters. In addition we use our sophisticated in-house AWD DynoJet 424x LINX to fine tune our calibrations. Our ECU tune enhances the following ECU functions/parameters, including but not limited to:

eg. Amazon, Victoria's Secret, PacSun, Dell, Staples
