Thanks BJ! Currently have a tune for JLT and Twin 65. Really looking at you twin 67 but didn't know if it needed a different tune. Any guess on a HP increase over the 65mm? Suggest a bigger elbow as well? Any tune tweaks needed adding an elbow?

None needed if it's our tune that you're running now.

TB to TB will net you 15rwhp.

Add the elbow and it becomes 25.

It's 40rwhp for the elbow and TB versus bone stock
