Gas Pedal Delay

Hot intake air (and the contributing hot engine bay) is really a separate issue from true throttle lag / unresponsive-ness though, it's best not to confuse the two. Killing VDC and running a modified throttle map will help.

Another thing that helped me (but may not apply to everyone else) - my dyno tuner had intentionally set the area of the A:F table that deals with low rpm + low throttle input (top-left-ish) fairly lean to conserve fuel on the highway. It's just a standard thing they do. I bumped those values back a little bit richer and it helped some (a bit more fuel available on initial tip-in from low throttle).

Reducing heat in the bay and focally in the intake tract is helpful in general; colder air makes more power. It's not a throttle-specific issue, however. FWIW, I'm pretty happy with Stillen G3's sitting on top of LTH's, but I've also made some minor related heat mods. Mostly, I've shielded the intake tubes with a thermal wrap (Thermo-Tec : Cool-Air Tube Heat Shield), and I also bypassed the throttle body coolant lines.
