I meant there will never be an aftermarket made chip...there are means of tuning the OEM hardcoded ecu through means of flashing and piggybacking which is pretty much the same thing. And no there were not ECU's available for the is300. there were piggybacks and flashes made available. Just wait a couple more months, you'll see what I'm talking about.
So in a nut-shell there are no standalone fuel management units for Lexus vehicles..please correct me if I'm wrong. But I've dealt with many newer model Lexus's, and have seen only piggybacks and reflashes...which do provide some good performance gains.

Reflashing and ECU generally offers more flexability than piggy-back ECUs since you can often change timing, air/fuel, transmission behavior, throttle response, etc, but piggy-backs usually just change air / fuel, and sometimes timing (poorly).
Regarding highway fuel economy, all modern cars maintain stoich air / fuel ratios very well at partial throttle, so there isn't anything to gain there.

I tried changing my IAT sensor voltage with a potentiometer on a '91 Acura Integra to adjust air / fuel ratio, but it didn't have any effect at all. There is absolutely no possibility that a current OBD-II vehicle would have any positive change either since it continuously calibrates itself with the sensors while at partial throttle.
