Fortunately I’m somewhat local (2 hours drive to their shop), but if you live far away you will need to send in your ECU since the current handheld doesn’t work with 2017 model. Anyway, it’s definitely worth the money since the cost difference of a 300 AWD and 350 AWD is roughly about $3,335 (for my area). I would take Uber for a few days and send in my ECU if I live far away...but that’s me.

Anyway, I’ll try to leave more feedback once I drive it more but the car pulls harder and smoother throughout the first 3 gears. Hopefully I can hit the track to get some 1/4 mile time soon.

Thank you Rafi, Simon, and the RR-Racing crew for making this possible.

Yes we dynod the car. This particular car was bone stock. 248whp is what a stock IS350 AWD would pull on a dyno, although I will emphasize that it was very hot that day and our shop is not climate controlled, so if IAT's were in the 70-80F range, we cold easily see another 10hp.

As far additional gains, the tune definitely benefits from a full exhaust system, not to mention headers (or our new Supercharger for that matter.

In any case, engine problems with these cars, especially during warranty period are unheard of. We have been running our shop 2014 IS350 supercharged with 360+whp for nearly 8000 hard miles now without a single hiccup. We have tuned 100's of ISF's (some of which are high mileage) and RCF's without a single reported engine failure, EVER!

I was wondering, what is the difference between your tuner and VR Tuner? I have not seen that many people talking about VR Tuned Gearbox. VR Tuned saying we can reverse back to factory settings.
