I think I got the update done on my '03 ES300, but i didnt get the final paperwork on the work done so i didnt know what it was called. But did you notice that the car now is more likely to shift at 3,000 RPM instead of 2,000 RPM like before. No i feel like i have to let off the gas pedal so i can shift at 2,000 RPM.

When i was using regular in my sc300 i noticed clattering coming from the engine when i was feathering the gas pedal. But now that I have switched back to premium the clattering noise is gone. You will hear the noise going away after 3-5 tankfuls of premium and i will never go back to regular. And of course you feel a difference in performance too.

I get the same noise and my mechanic said that it was normal. He works on a lot of sc's so he knows.
