CHOICES - We tune with SCT and HP Tuners software for the 21-23's.

• SCT - If planning on staying naturally aspirated or if you already have a supported SCT device, go with SCT.
• HP Tuners - If you have future plans for forced induction or already have a supported HP Tuners device, go with HP Tuners.

Omega is still great no matter which one you go with! Just different software, hardware, and programming methods.
