I see some here have installed a larger throttle body, and im wanting to know what kind of performance gains, or gains in general you noticed after the larger throttle body was installed ?.

 

I have the Fastman 52mm. Better throttle response, no noticable HP/TQ gain/loss

 

You should gain power at WOT.

 

i had the Hughes Big Gulp on my ram, which is even bigger than the 52mm and i coupled it with the FI Airgap, and omg... but i did it all at once, so i couldnt say how much just the TB helped. but it did sure whistle like a ****.

 

It will depend a lot on what other mods if any you have done.

 

The Fastman 52mm is the way to go on a stock or lightly modified truck.

 

The Fastman is a god.

 

By itself, not much. But with supporting mods? A pretty big difference

 

If you tow at all and like bottom end stick with a 50mm. Even for a 360.

 

+! completely agree!!
