Replaced the TB on my 3.9 with a stock 5.2 It idles well but hesitates under hard acceleration. Is this the ECU learning as many posts have stated? Thanks for the help.

It takes a few hundred miles for the computer to

Give it some time.

Yes the systems on these trucks learn and adjust
to individual driving habits for best performance
and economy.
If you change the throttle body the motor will
be getting a bigger charge of air and it will
take about 50 miles for a short tearm learn and
after 2 3 hundred it will be fully adjusted to
maintain the proper air fuel ratio and give
you more power.
Almost every truck we have upgraded the TB on
also showed better gas milage as long as you
drive normal and do not get a heavy foot playing
the added power you will get.
A cold air intake system or at least a drop in
K&N filter will also give you better flow, more
performance and better fuel economy.

idle blip it again and it coughs
