Now I've seen some strange claims in my life, but this has got to be the best of them all.
Their honesty is commended though LOL.
Am I seeing this right?
If I go ahead and install headers, and get their tune, I'll be paying 500 bucks for maybe 6hp ( taking into consideration that dyno results aren't always consistent ) ?????
Seems ok to me? They are offering a custom tune based on the modifications of your specific vehicle and likely will provide the appropriate parameters for the car for long term reliability. Such as appropriate a/f ratios so you don’t blow the engine prematurely. In this case it goes beyond just HP gains.
Although, I would say the best tune will be done on a dyno or during a track session to ensure proper a/f. So that’s my only gripe against mail order tunes.
Do have to mention that I am new to Lexus vehicles. But I have done tuning sessions with the several mustang cobras that I’ve had and the few Dodge Vipers that I’ve had.
From what I know(been told) this could actually be very beneficial. Hopefully someone else can chime in on if this is true or not since I'm only a couple months into owning mine. But the salesman that sold me my GS-F had previously owned a RCF and a GSF that he had modded pretty heavily. He was telling me that you can do intake, headers, exhaust, ect, ect, ect but at the end of the day, the ECU will "de-tune" itself back to a stock(ish) HP/torque rating after a few thousand miles. He said that in order for you to keep those gains, you HAVE to do an ECU tune. So if this is true, then the $500 to tune your car to your mods would be beneficial. But TrevorR is spot on, the only way to do it right is on a dyno and see where you A/F ratio is at. Anyone else heard of our cars "de-tuning" themselves?
RRR doesn't modify AFRs in their tunes. If you read through the history of them, you'll see they change ignition timing to get more power. They're just as afraid of someone running bad fuel as Lexus is, so they leave the AFR alone.

Well you have to give it to RR racing for their honesty, talked to them before and they impressed me as no BS, straight shooters. Do keep in mind that the 6 HP you mentioned is on top only and you have to factor in the 17 WTQ increase down in the power band.The other important variable that an excellent tuner can tweak in an ECU that does not reflect in a dyno sheet is a car's driveability and response, both of which significantly enhances the driving experience if done right.
Can any other tuner extract more? There is no else that seems to offer tunes for the GSF/ISF so who knows. Whether or not it's worth it is really a personal choice but if Im putting on headers it would be a tough choice for me NOT to go with the tune because given the limited mods you can do to the platform, other than supercharging it, why not just do it. But I get it that the bang for the buck factor is low.
As far as an etune vs a dyno tune on a simple header install, I doubt the gain, if any, will be significant enough given an addition of a header is simple, assuming there is even a tuner who can tweak a GSF/ISF ECU on a dyno.

That's not entirely true, there is now open software available that has unlocked the bootloader of the RC-F/GS-F and are selling their tools to experienced tuner shops to allow for etuning and local Dyno tuning.
At the moment one shop out in Colorado I believe had some fantastic gains on the RC-F. The providers of that specific tuning platform are competent software engineers and are adding quite the feature set.
E85 support with flex fuel integration
Different fuel maps per transmission mode (eco/normal/sport).
it will take a little while for tuners that are interested in tunning and switching software. But at the moment there is quite some competition growing.
E85 if they release it and a competent tuner provides a tune for it. Some interesting results could be uncovered on an otherwise stock vehicle.
@designo wait it out and see what happens if more tuners jump on board to ovtuner platform.

RR Racing tune.... 500 Bucks for 6hp?
