Hi Zach & the rest of the Delicious team.
First of all wanted to report that my car has been running awesome on your flex tune for close to 12months now. On and Off track.
Chopping plenty of "faster cars" to great amusements.
Anyway I want to try swapping up-to (or is it down to) the 3.125" pulley on my vortech SC.
Want to know if this will need a re-tune from you guys?
Cheers
Solomon
