I stumbled upon this in the 3IS forum and am curious if anyone here has implemented this tune on their 4GS.

Does anyone have this tune? If so, what's your feedback on the change? Can you revert to stock mapping easily?

Theres been a number of threads in the past about it, I don't think it really does a whole lot. ECU's in these cars are pretty locked down. I do see this thread for another tune on a similar engine, haven't read thru it yet. Not sure if I've seen any GS350 owners actually do it, I'm always cautious with any "tunes" like this if its not for a turbo based car.

Maybe there has been more progress on these tunes from the last time it was discussed. I see some for the other models.

The ovtuned link references 2014+. I wonder if the ECU's are different for the 2013's?? I would try this if they worked for the 2013's.

Hit up their customer service, they are pretty responsive and they have been getting some nice numbers with their supercharger. The ISF Supercharger was successful and so is the RCF/GSF. I know RRRacing is coming out with a SC for the 2GR-FSE (should be sometime end of the year I think? or next year) since it can be applied to 3 platforms (IS, RC, GS), but will have to wait to see what they can produce and if the price to performance gain is worth it.
