Tuning Facts and FAQs

RR Racing has pioneered Lexus ECU tuning.  We were the first to release a tune for Lexus ISF in 2015, then the first to tune the RCF and GSF, we then developed the tune for Lexus IS350 2006 to 2013 and finally IS350 2014 through 2017.  Last year we introduced the best tune for Lexus IS250 available anywhere.  So needless to say, we know a thing or two about Lexus tuning.    We would like to clear some misconceptions customers have regarding tuning a Lexus, as well as answer some FAQs.  Some of these are based on experience they may had with older cars, and many of these are based on erroneous information they get from other tuners.

Modifying a Lexus Vs. a Subaru — Which Brand Comes On Top?

As many of you know, the roots of our business is in many projects modifying Subaru WRX.  In the last three years, we have been hard at work developing the Lexus IS/GS/RC350 platform and making sure that our customers can extract the maximum performance from these cars, at a reasonable price. Our IS/RC/GS 300/350 supercharger kits now produce a reliable 445whp output, all while maintaining the excellent reliability of the stock engine and transmission. We offer a range of other products, such as suspension and brake upgrades to bring these cars up to true ultra-high levels of performance.

So how does the 3rd generation IS300/350 platform stack up the wildly popular Subaru WRX and STI’s?  We did a little analysis, evaluating everything from purchase price to cost of upgrades.  Here is what we found:
