GS 350 Programmer, Tuner, ECU thingy!!!

I'd like to think they did a pretty good job of tuning this motor and with 2 sets of injectors along with high conpression it's not going to be a simple tune for your average dude in his garage trying to tune his catback exhaust and k&n filter lol.

What Schexus said.... Don't forget these cars are tuned around fuel economy for a good reason, I'd say you'd gain some good RWHP out of a good tune.
GL to you if you ever try, but don't cry if your ECU is unusable lol, I've read that someone sent theirs out and Lexus apparently has a fault switch, which fries the ECU if you've tried TOO TOO many times.

I don't know maybe I'm an idiot, but it seems like your two statements contradict each other. I could see if you said that our cars run rich and therefore could be leaned out for more power but how are you going to make more power by richening up the mixture without adding more air as well?

You're by no means an idiot, it's probably my bad wording, apologize for that .
Tuning doesn't involve just air and fuel, it also involves the ignition system, VVT, etc. etc.
I believe the heads on the 2GR-FSE's are built to flow really well also!
My buddy a while back, threw up a mapping of the 2GR-FSE, the blueprint schematics of it and basically if the ECU is unlocked, there's plenty of potential in the engine.
The same went when he stumbled across info on my 3uz .
