Whats up guys. I have an 03 HD with a unported eaton. Stock exhuast. 6lb lower, JLT big air intake and gen 3 killer chiller. Iat2s are always around 70-90F. When my tuner dynoed it , it wouldnt go above 8-9lbs because of slip so I put a 100mm idler on there and its a very consistent 10lb now. Before the lower, with just an intake Id hit 7lbs in the same temps. But shouldn't it be 12-13? Just curious before I go and put a upper on it.
