Uprev retune 4/22

The manifold is more for giving more mid range power and a bigger, and broader power curve. Not top end. Some people it helps and some people it hurts top end but the main use of the manifold is to get peak torque sooner and hold longer and make power between 2500 - 6500 rpms more so then 6.5 - 7.5k rpms.

So basically, i see you making 319whp if you did previously but if you overlay graphs, your powerband should be more broad which means sooner, higher, and longer holding torque in turn providing hp sooner but not so much more of it.
