hey so i have an 05 xb1 with full exhaust, intake, and throttle body spacer. im looking to find an ecu swap or computer tuning or something... what does anyone reccomend? price is sort of an issue but i wanna hear all ideas. any responses are appreciated

 

Emanage or emanage ultimate will do just fine. The AEM FIC is a popular piggy back among scions as well, but it would be a waste of $ for tuning an NA car because it can only retard timing.

You will only see a hp gain if you switch over to premium gas and have it tuned with that. Cost wise, you are looking at about $500 to $900 for engine management with plug and play harness, and $400 to $550 for the tune. Is it worth it? That is up to you.
