In this age of getting the best possible regarding economy, is it worth getting the injectors cleaned ultrasonically? Please don't go on about not buying a Scoobie for economy blah blah, I can get a set of reconditioned injectors for £85 but will there be an improvement both in terms of economy and performance - both of these are claimed by the vendor. Car is a 96 WRX with around 80K on the clock.

Thanks
