bro, when would you like to do the ECU flash? RR racing told me they need to flash your car first then they could do it on mine~~

Yes I'm having my car done hopefully this weekend. I have to check with him as to when he has time. I will be the first GSF with a tune and the Super charger. Cant wait.

what do you expect to have a horse power when you're done ?

with the ECU upgrade maybe an extra 10 to 20hp but with everything including supercharger I'm aiming for 600hp to wheels who knows maybe more depending on what I can do but whats the point of having so much torque if you cant really put it down.

klimber

that is awesome, what will it cost?

contact rafi at rr racing for info on mods and tuning capabilities.

600whp is almost the power limit of street cars, even a Ferrari F12 which has 731HP doesn't put down 600 HP at wheel. It has 589WHP at wheel and a 570HP 458 put down about 450HP at wheel, which equal as our car with I/H/E and tune. 600WHP is really a lot, need a 325 tire to handle it, at least should be 305. For our stock wheel, I think the max might be 295, and it will have some traction problem when floor the gas. However, lexus has a better traction control system than BMW. The one on my previous m4 is terrible as hell and it has problem handle 480WHP/480WTQ. Since the supercharger has a liner output, I think it should be better. I heard that the kit is about 8000USD ,with a that install everything, I believe 10000 should be fine. Sound a lot? yeah or no, maybe you can spend 10000 to buy one jacket like Zilli,10000 might not be enough,or a phone like Vertu. So if we want some power, just go and do it, RR racing is really a great company and pioneer in this field and we are glad that they bring us such great products.

With the direct injection and high compression of these motors, 600rwhp is going to be difficult without a modification for fuel. A lot of people are running meth injection now to increase the octane enough to avoid detonation. It will be particularly difficult with the Lexus because it seems they suffer from excessive drivetrain loss. A lot of the RC F guys were dynoing well below 400rwhp, I even saw some as low as 350rwhp. It could be the dyno of course, but the majority of them seemed lower than they should be. I hope it works out for you though, it should be pretty amazing! Even if you don't hit the 600rwhp mark, the car should feel like a rocket!

Any reviews on this (http://tuningtechfs.com/lexus-gs-f-performance-tune/) tune? Does it void the factory warranty?

I believe there is no chip tuning on it's own that will give your car more power.
Just like the 3rd Gen V8 cars. I genuinely believe there is no power gain from an ECU flash only.

I'm more interesting in something that tweaks the gear ratios. Even in sport mode, the car is trying to get to 8th gear as early as possible. It makes it feel sluggish when I need to get on the gas.

Isn't your solution "Sport+" mode?

JColeGSF

Yes. Currently, that’s the solution. Sport + just feels like a harsher driving mode. I like the smoothness of Sport, but it seems like it could be better at filling the gap between Normal and Sport +. I was just interested in knowing what was out there and what might be possible for the car. I guess I was also thinking there could eventually be a solution to quicken the transmission response in terms of downshifting when the gas is pressed. I don’t know if a tune is even capable of doing something like that.
