Who makes performance tuners for toyota cars? How can I get one?

I own a 2007 Camry LE, 2.4L 4 cylinder engine. It is little sluggish. I know about perfomance tuners for pickups (superchips, hypertech, ets). Is it possible to get a plug in type tuner for toyotas? If so where and how do I get it? Does this void the warranty?Who makes performance tuners for toyota cars? How can I get one?
Toyota ECU's are pretty much crack proof by the general public but there are places that can modify the roms slightly.But as far as your Camry goes it may be that it is a heavy car,with an underpowered engine.If you were to modify your ecu in any way it would void your warranty.My suggestion is buy a sports car in addition to your camry.I mean start with a basic performance car like the MR2 or my real favorite,Lotus Elise.Who makes performance tuners for toyota cars?

check out superchips.com if you want a programmer. and check out jetchips.com if you want a plug and play chip. they will not void warrantyWho makes performance tuners for toyota cars? How can I get one?
If you would like your car to be tuned differently during different weather or city use, highway/freeway use, then fix up an Air fuel Controller( SAFC2 or any other brands could work too) eg. HKS,Apexi....



hope it helps
