yesI'm seriously contemplating getting a second ECU for my 2006 GS430. I definitely want the ECT PWR mode to be as aggressive as possible.
But I'd like the car to stay reasonably calm in normal mode. Is it possible to alter just the VVTi tuning, make the transmission a little more refined and leave the stock throttle response? Just in normal mode.
I really like the dual personality of my 3GS with the adaptive suspension modes. It's like my Top Gun attack toggles.
