I have a 06 4.8.
So far: Cold air tube stock box, K & N drop in, TB bypass, Predator, Cut out.
What would be a good set up to gain high end HP while keeping low end torque.
If I can keep the low end power where it is at I would even be happy, but a little more low end
would not hurt either. I would like to get to a low to mid 13's with anything but spray or a charger on a stock rotating assembly.
