This one doesn't seem as responsive at the gas pedal like my 350 is but I think this is because I have headers on that one. Obviously the 370 has much more power but my 350 outdoes it on gas pedal response time.

What can I do to get that power back without putting headers on the 370? I was thinking about a Stillen cold air intake. One in particular, Stillen Long Tube I hear will add 16 hp but will it add that responsiveness?

Putting headers on this one will be a challenge without having a shop do it and I don't want to go voiding my bumper-to-bumper warranty. Trying to save that for later on down the road mods.
