Turn that 60HP or 90HP into a wheelie machine! These 120HP tunes give you the bottom end and midrange the 900ACE should have come with from the factory. 

These tunes are worth it on their own, but pair it with any of our other offerings for even more gains. These tunes work great with Solas 12/14 Impellers, Free Flow or Rear-Exit Exhausts, the 'Powerbox' waterbox and many other performance parts!
 
****These tunes are only offered in person! Please call to book an appointment. ****
