input on low-midrange torque
 

Looking at the M370 manifold I really like the midrange torque gains, car doesn't spend a lot of time in the stratospheric rev range. Would benefits be seen with an otherwise stock intake system (K&N drop ins) or should I get post MAF tubes/hold off until getting G3's? Can I run this safely without a tune for the time being or to keep AFR safe will I need one immediately?
