i put in a k&n intake in my 00 LS and i noticed increased performance in the high end rpms but the low end revs are lagging. i was thinking about a throttle body spacer..

many of the sites ive looked at advertise IMMENSE power increases in the low to mid range rpms.. i think they're exaggerating.. any opinions?

thanks

p.s. i think having programmed fuel injection has a lot to do with how the throttle body manipulates the air flow.. but how does this translate to my induction system?
