Does ECU tune also affect/revise throttle input mapping?
I am considering getting a throttle re-mapper, i.e., Sprint Booster or PedalBox. I understand these products simply adjusts/re-calibrates the throttle pedal's potentiometer to run a more aggressive curve instead of a flat, linear throttle input. 
Given the prices of these products, however, does an ECU tune also revise/adjust the throttle position mapping? Would be nice if--two birds, one stone, etc.
Or, is an ECU tune strictly limited to revising just the fuel mapping? If an ECU tune does indeed revise the throttle input mapping, what other adjustments or changes are made (generally speaking, of course)?
My car is stock (other than axle back mufflers & K&N filters, so yes...stock).

An ECU can sharpen up the throttle, but it depends on the tuner/type of tune.
In most cars I've tuned, simply increasing the timing advance will provide sharper throttle input and of course more timing is given to increase power, so therefore sharper throttle is a by-product of power tuning (although not necessarily, blah blah blah)
My guess is that with an ECU tune, you'll be better off.

I would like to know this too.
Judging by Posts of some users, directly after they applied a tune, it seems to be really sharpened up - however once driving down the road in Grandma-mode for some time, the car learns it again and you will have that lazy mode back.
Solution to this would be a throttle reset even now and then.
I really would like to know what the tuners here say about that?

Throttle response improvement from ECU tuning
I am considering getting a throttle re-mapper, i.e., Sprint Booster or PedalBox. I understand these products simply adjusts/re-calibrates the throttle pedal's potentiometer to run a more aggressive curve instead of a flat, linear throttle input.
Given the prices of these products, however, does an ECU tune also revise/adjust the throttle position mapping? Would be nice if--two birds, one stone, etc.

Features of the tune include:
• Improved Performance and Drivability
• Higher Torque request for TCU
• Speed limiter removal
• Improved throttle response
• Rpm and shifting limits can also be increased
The price price for an ecu tune is $595. We also offer a Flash Loader with 4 map pack (stock, valet, tuned premium pumpgas & 100oct Race) for $795. More information can be found here http://oetuning.com/blog/?p=727
With the purchase of a flash loader, your ECU does not need to be removed for tuning and you can switch between settings at you convenience.
TCU upgrades are also available for $395 (send in only).
All purchases also come with free reflashes should the dealership write over your tuned settings.

Can ECU and/or TCU tuning eliminate the 'auto-learn' feature that reacts and adapts to driving behavior so the car remains tuned 100% of the time regardless of driving habits?
