How much extra air (Intake) is enough for a stock 5.3?

[Oshkosh]

Ok engineer types, save me the research and the headache from all that thinking , on a stock 5.3 how much air does the TB actually take in at maximum intake?
The reason I ask is a stock setup runs for many people just fine.
Then you have the minor intake mods (filter in stock box) and it livens up the motor a bit,then you have the full blown CAI's with big open filter ,big volume tube etc....
At what point is it overkill? At what point doesnt the stock engine responed to any more potential intake?

If your engine doesn't know what to do with the extra air, then there is no use for it.

Looks like you found a use for more air

It looks like from your photo you found a way to pack some more air.
Guess I need to purchase a dyno to find that point, maybe a flow bench to get her breathing better.
Wait, I want the most efficient with the stock motor without wasting.

Your computer still needs to tell your engine what to do with the extra air. So folks who install CAIs, or modify their airboxes really aren't getting anything out of them, until their computer is properly tuned for it.

Hmmm

It certainly appeared to liven up a bit opening up the air box with the K&N, Does rev easier/quicker shifting up into 2nd. Just seat of the pants but have been around enough toys with motors over my 46 years to pickup on such things .
I am planning on a tune come spring, get to busy during the winter to play around with my daily driver.(State snowplowing contrator,snowmobiling, skiing)....
Would like to do the vette servo and 4th gear servo but my tranny guy has tried to talk me out of it....Saying it would shift hard into 2nd around town.Would your tune address any potential slamming around town?

I am surprised he is talking you out of it, it beefs up the 1-2 shift. We had yet to see anyone (even pre-tune) that wasn't happy. WE will lower the transmission line pressures to make sure it isn't a violent shift though.

Well you at B.B come highly recommended ,thank you for your input.
I am happy to hear from many that they haven't had any negative results from the servo swaps.
I was hoping it would be a positive upgrade all the way around, performance and longevity ,a nice match for a daily driver and sometimes tow rig....
I like the truck and love to make things better as I go. Get the most bang for the buck as they say. When I step on it ,I don't want to hear it say what? lol
If I can upgrade and not lose mpg's than even better.

The Vette servo has more surface area than the OEM, which provides a more positive band engagement with the same level of pressure.

That makes sense

The Vette servo has more surface area than the OEM, which provides a more positive band engagement with the same level of pressure.

That makes sense , less slippage and a more positive engagement means less heat and heat kills transmissions....I assume it would be the same with the 4th gear servo, less hunting when in O/D, less heat....I am pretty good about not abusing my O/D..
My Dad had a 1984 Suburban with a 700R4 and towed a 31' Airstream the trucks whole life, the original tranny made it to 145,000 miles.Yearly fluid and filter changes and keeping it out of O/D when not on the open road(towing). Infact it didnt blow till my brother got his hands on the truck. Many of dads buddys had two or three rebuilds at that point...
