is there anything i can do that really works? am not a big believer in 'cold air intakes' and am skeptical about the low cost ecu mods. it runs ok, but need some extra smash for passing. have looked at the 4-2-1 headers, wonder if anybody has tried it and found that it really makes a difference. dont want to spend the big bucks on a turbo- or super-charger. thanks
