How to increase throttle response?

I'm Not Right in the Head | Random Rants and other Nonsense1st Order Logic Failure: Association fallacy, this type of fallacy can be expressed as (∃x ∈ S : φ(x)) → (∀x ∈ S : φ(x)), meaning "if there exists any x in the set S so that a property φ is true for x, then for all x in S the property φ must be true".

Liam...let us know whats up
I hate my AFM and would love to replace it
I'll probably will have it all looked over in the next couple of weeks.I'm Not Right in the Head | Random Rants and other Nonsense1st Order Logic Failure: Association fallacy, this type of fallacy can be expressed as (∃x ∈ S : φ(x)) → (∀x ∈ S : φ(x)), meaning "if there exists any x in the set S so that a property φ is true for x, then for all x in S the property φ must be true".

Not a lot of point in spending a bunch of resources on these old ones, maybe latter down the road though if the opportunity is there.I'm Not Right in the Head | Random Rants and other Nonsense1st Order Logic Failure: Association fallacy, this type of fallacy can be expressed as (∃x ∈ S : φ(x)) → (∀x ∈ S : φ(x)), meaning "if there exists any x in the set S so that a property φ is true for x, then for all x in S the property φ must be true".

Let's make this an easy answer: afm is mechanical vs. maf is digital,and that in it self is a difference,throttle response, one can't argue that as far as the horsepower one will gain? I say put it in do a dyno test.Then you will have paper work in had for proof rather than get 10+ different answers which all can't be correct, and I have heard all good things not one thing bad from the people that have used it.Your signature picture has been removed since it contained the Photobucket "upgrade your account" image.

So it took about 30 minutes to install (probably an hour and a half without a full shop and many years experience doing this kind of thing).
The AFM this replaced was about 6 months and 1000 miles old. Everything on this engine is pretty much 100% fresh.
Right off the bat, definite improvement. Smoother idle and no bounce when the throttle gets "tapped" in overall drive-ability there is a very noticeable improvement in throttle response and the subjective ass dyno tells me that it's gained some torque and a wider power band.I'm Not Right in the Head | Random Rants and other Nonsense1st Order Logic Failure: Association fallacy, this type of fallacy can be expressed as (∃x ∈ S : φ(x)) → (∀x ∈ S : φ(x)), meaning "if there exists any x in the set S so that a property φ is true for x, then for all x in S the property φ must be true".

Somewhere on down the line it becomes converted to a digital signal, but so does an AFM.paint sucks

I keep pretty tight records on this car so after a little while I'll have information on general fuel economy and more (albeit subjective) information from driving it in different conditions.
And yes, if I get a chance, I'll run it on the dyno and then will have some comparison from the last time we ran the car with the AFM.
After that... I have some evil plans (it'll be a while though).I'm Not Right in the Head | Random Rants and other Nonsense1st Order Logic Failure: Association fallacy, this type of fallacy can be expressed as (∃x ∈ S : φ(x)) → (∀x ∈ S : φ(x)), meaning "if there exists any x in the set S so that a property φ is true for x, then for all x in S the property φ must be true".

It is not "stock" an awful lot of things have been changed not necessarily just bolt on stuff either, it was dialed in on the dyno prior to this being slapped in.I'm Not Right in the Head | Random Rants and other Nonsense1st Order Logic Failure: Association fallacy, this type of fallacy can be expressed as (∃x ∈ S : φ(x)) → (∀x ∈ S : φ(x)), meaning "if there exists any x in the set S so that a property φ is true for x, then for all x in S the property φ must be true".
