XB performance chip

Does anyone if there is a performance chip out for the 2005 xb?
How do I get it?
How much does it Really change?
Does Toyota approve (warranty)?

Usually, performance chips for Toyotas don't yield any performance gains.

"performance" chips usally just make your car run rich (more gas to the engine). They may give you a few hp, but they will cause your car to start spewing out thick smoke after a year or so (after you Cat cant take any more) and fail to meet any emission test.

clearly, the factory air intake is a joke.

What are people doing to increase performance?

i saw an xB with an AEM intake.

BlitzJapan has a few things for power... i believe they were developing a s/c or turbo for the 1.5. they also have their air intake system, NurSpec cat-back exhaust, and turbo timer and boost controller. and DC sports also has a nice 4-1 ceramic header and their own exhaust being developed. there should be more but thats all i know for that engine.
