Hi again...last question..lol. Same car...2004 Tib I-4, 5-spd. I see these resistor kits on ebay saying gains up to 20hp. Does this really work? If so what size is the resistor that is used? I just can't justify $4.00 for a resistor and $3.50 to ship it esp. when I probably have the exact size resistor here with my pinball machine repair parts. Well if anyone can help me out with any of these 3 questions I would greatly appreciate it. Thanks Greg
