Please Explain that one......... My low boost (When it's there) 
performance is nothing short of Phenomal!

Hunnnhh, How's dat?? 4 valve's are for HP 2v's are for torque, Torque is 
partly a function of turbulence........  4 Valves were introduced to 
allow a engine to breath and fill/empty  it's cyl's at high RPM's not to 
increase it's low end torque.
