I am currently setting up a group buy for the RR Racing Tune for all F-Sports and F's.
I have 10 people currently wanting in on the group buy. Of course the more the better.
RCFs and GSFs will have to ship their ECU to RR and they will have to tune it for you but Simon from RR will guide you through the process. It should altogether take 2-3 days as RR works fast and will overnight your ECU back.
PM for more details and if you want in on the group buy.



If you are located in Houston, let me know and I can add you to the Houston F's groupme.

RR told me to get a number of people first then theyll give me a price per person.

What kind of HP gains can be expected for a totally stock GS350 and putting a tune on it with no other upgrades? Would it be worth it? If so, I would be interested depending on price.

Their website for this tune states 10whp for a stock setup, 15-25 with a full cat back exhaust, and 40-50whp for a full cat back + headers set up.

I have the tune, and I don't know any idea about realistic HP increases but I would say it was definitely worth it for me. I have it with my apexi accel and the car is extremely responsive and fun to drive. I've covered my thoughts on it in other threads. Especially with having awd it can shoot off the line pretty well.

Count me in.

I call BS. I would like to see some proof? 40-50whp for just a header cat back etc. If the cat and headers were so restrictive I would think Lexus would make them better to give the gs a power boost it is lacking in the performance sedan market

If the tune was available via OBD II, I'd be all over this, but if there was 1 ECU out of a 1,000 lost in the mail, it would be mine.
