If you do this you can decrease the IDC's for the given injector.
Now improve VE by means like the Killer B Holy Header and head work, PnP of the intake manifold, piston design...etc....and then you will make more power at lower rpm's and make more over all because you are wasting less power through parasitic loss!
You make more with less! Less is more
Ohh yes, all this is true!
I thought what you were saying is 'Take a stage 2 STi, tune it, check IDCs. Now take that same car, slap on ONLY a header, retune, IDCs will drop'. I just dont see that happening
