You are in the red area after 6500rpm . I assumed that the red is a no go area . Is one not risking engine damage by using the 6500-7000 rpm area ?
I am maybe being to careful .
MY 4/4 has K@N filter, Librands Manifold ,Williams remap ,Brake reaction Bars and panhard Rod and find the best range is 3000 to 5000rpm .
