Replaced M370 with z1 intake plenum

Eighties Meta

Unproven but i just feel it chokes off my top end. M370 has 83k miles driven on it. I didnt care when doing 3 or 4 track days a year and not thst much extended highway driving but now thats reversed, the car will do no more trackdays and most of commute is how highway. I want that 10-15 hp back on the top end, if i can get it or add it. We will see
