What's the difference between SCREAMIN' EAGLE PRO SUPER TUNER and SCREAMIN' EAGLE STREET TUNER ? Just got my V&H True Dual and Monster Rounds , now i need to know the difference on the Tuners .

 

If you take a look at Harley's SE catalogue you will see the official line. The clue is in the names, the Street Tuner being intended for maintaining EPA compliance when modifying a street motor, the Pro for more radical tuning. Be interesting to see what experienced users have to say about them both!
