The exhaust tip on mine looks like a lump of coal... does anyone know if there is an aftermarket tuner in the Austin, TX area? I'm not looking for power as much as a cleaner a/f ratio and better mileage - that damn gas pedal will kill any fuel economy no matter how much you tweak!
That said - who has used any of the tuner black-boxes out there? I've only seen the XEDE on the Protoge' Garage site. Is this worth the expense or will a good re-flash tuner do a better job? (screwy)
