Have you already had your truck tuned?

Swapping an intake wont help much with throttle response.

 

Seems a bit expensive and involved when you can just tune your truck and get more throttle response and maybe more power and fuel economy while you are at it.

 

Yeah have tuner cold air intake and exhaust... Do you know if the new 6.2 throttle body will work through? Or will it have codes?

 

you can buy larger throttle bodies, but in the end its electronic, so response will only be as fast as its programed.

What makes you think the 6.2 one will open or shut any faster?

they make a thing called a pedal commander which apparently works awesome.

 

Yeah if you really want the utmost throttle response go back to a cable and get away from fly by wire.. I would think you'd need a specific tune. And not to mention you are not cramming more air through, so even if you put a bigger throttle body on it, I doubt you would gain any power as your motor in stock form can only flow so much fuel and air...

 

Well I looked for larger throttle body but couldn't find any for 5.3 unless you get machined... Also reading this forum someone suggested to replace with 6.2... I asked same question never got a response... But yes the 6.2 tb is larger so would have more airflow.. So in my opinion I would think have more response and power.. Probably not much

 

swapping the throttle body won't do anything for throttle response.. .

get your stock throttle body ported/polished... that helps with throttle response...

A ported throttle body definitely helps with better/quicker throttle response and acceleration - I have ported throttle bodies on both my Camaro and Suburban... contact Bo White - he's the porting guru... makes a big difference... you can contact Bo White at: Portsculptor AT bellsouth DOT net

 

Thanks montess

 

Have you done the paint stick under the throttle assembly MOD???

 

No but I know what you're talking about with the paint stick

 

No but I know what you're talking about with the paint stick

It does work to improve throttle response some. However; you're gonna have to address "torque management" in the appropriate module, in order to see real "mechanical linkage" type response.

 

I appreciate it.. I'll look into the torque management.. I was hoping someone knew if the new throttle body would work (like plug and relearn) or if would throw a code

 

What we are getting at, is that even if it was plug and play, it would be a waste of money... Just because it is a bigger throttle body, that does not necessarily mean your car will gain more power. Yes, it is capable of flowing more air, but unless the rest of the engine is also capable of flowing more air, you will gain no extra power, or not enough to justify the cost. The motor regardless of how much the throttle body will flow will only put so much fuel with stock air flow levels.

 

I completely understand what you're saying and I appreciate everyone's help... But it's already bought... I just wanna make sure before I do it and need something else done... So if anyone knows if it's just plug and play or if you will have to get additional tune please let me know

 

Can return it.

Did you get a different intake boot for it? I believe the 5.3 and 6.2 use different ones. It's why the intakes aren't interchangeable

The intake swaps right over... Only thing I don't know is if the computer will read it properly

 

*intake tube. The diameters for the coupling between it and the throttle body are different. I believe

Oh yeah the size is different but it comes with a adapter

 

Reason why I say that is because my cold air intake fit my truck or the 6.2 L
