I am runnign the Haltech because about 95% of Turbo IS300 that go standalone are running it and its what Lance @ Toyomoto put in the car when I did the initial turbo kit.

Frank @ SFP tunes Haltec and AEm. He is an AEM dealer. I would be really surprised if he couldnt get you an AEM. He has put them in every car i can think of.
