ITBS porting with bigger butterflies, worth The Money for power gains ?

[M3NTO_M]

Just a quick topic for anyone that done throttle body porting with bigger butterflies from VAC.

Just wondering from anyone's experience.
ls it really worth $1,500 bucks just to do that service from them ?

In there perspective. It's a 5-10hp gain?
anyone can show proof it does actually make a gain?


I think this was covered in a very old forum.
I'm new here.
just would like some information before I click purchase or not..

Thanks !

Also anyone ever refreshed Itbs ?
like service?

No porting just service?
Grease up butterfly shafts, cleaning, adjust?
Currently In process of rebuild/refresh of engine components



Thanks

You need porting to maximize the gains, with tune, is a good mod.

Spend money on porting the inlet port first as that is the biggest impediment to flow

Not worth it.

Yes. I did this when I rebuilt my motor. Cleaned all components and made sure they opened/closed without an issue.
