I have a 2009 Scion XD with only 115,000 mi on it. I currently have an aftermarket intake and exhaust. Does anyone happen to know where I can get a tuner or programmer for this car to get rid of the check engine light codes as well as get rid of the speed limiter and improve the accelerator pedal response in desperate need ASAP?

 

Those mods shouldn't require any changes to factory ECU maps. Which codes are you getting? Were they there before upgrades?

Are you planning on any future engine mods like cams, larger valves, radiused valve-seats, big-bore high-comp pistons, maybe even turbo?

You can get AEM FIC-6 30-1910 unit along with AEM UEGO wideband to start. Update maps as you get AFR feedback. Then update again to fine-tune with each additional engine mod.

I want to turbo but can't find one. I have an exhaust code from the aftermarket catalytic converter. I've already changed the sensor and it's still throwing an error code.
Mainly need a tuner box or computer which I can't find either.
