2004 Scion xB Conclusion - Import Tuner Magazine

Conclusion
With solid gains in both horsepower and torque across the entire powerband, we definitely recommend modifying the xB. while we won't promise that the addition of bolt-ons will help your xB win any races, it will give more power and torque for the daily commute, and most likely increase fuel economy as well-provided the new "race car" noises don't prompt lead-foot driving. The initial drop in power above 6,100rpm was a concern, but became a non-issue with the addition of the last modification, and all but proves there's more to be gained with a good tune.
