This is what I think.... If you are a tuner, the new IS might not really be your taste. Did you guys see the picture of the engine bay? it is completely covered with plastic. Fine maybe you can take it off. What I've read from Modified Mag, all the new cars that are coming out will be equipped with extremely smart ECU. Even tapping it with an E-manage or SAFC won't do anything. The ECU will know that it is being tapped into. Also, bolt on performance parts will not work. For example, lets say I install an intake which gives the car +10whp, the ECU will detect that and make adjustments to make it back to +0whp. Conclusion: No gain at all. The reason for this is that car manufacturers does not like their cars to get modded. You might ask why, it is because it hurts their reliabilty. So after a 18 year old modify their car, and the car breaks, who's fault is it? the kid or the car manufacturer? People will say, the car manufacturer. also, let me advise people that are planning to change their cars, moving from an IS300 to an IS350. Our engines are turbo proven, meaning that we can modify it up to +450 whp or more. That is because we have a beautiful engine with a sister engine being the Supra engine and we can just swap internals. Where is this 350 engine coming from??? How good is it to boost? Can it be boosted at all? If you guys want the Modified magazine article, you can get it at the newstand.
