just wondering if a 80 mm throttle body will help my throttle response at all ,im getting my tune finished this week and i have a bbk 80 mm i thiught i wuold throw on before he plays with the fuel air mixture any opinions,

 

what else you got done? I doubt you need that tb right now.

 

iv got a descent comp cam ,cai ,headers.

 

i dont have any response at initial punch of throttle i thought about boring out mine but i already have this one .

 

you got an 03 and up truck? DBW throttle body will do that. In my moms 04 yukon I can stomp the gas and let off quick and the tach will barely move..

 

04 sierra w 6.0 lq4 3.73 gears .what do you mean dbw throttle body?

 

Drive By Wire throttle body. It's electrical, giving it a bit of a delay.

 

a bit is an understatement but that is with a stock tune

 

Throttle response can be modified in the tune if necessary for the electronic throttle bodies.

 

stock TB is 78mm. no reason to go to a 80.
