Since I have the stock VIII DV and the HKS bov on the same setup (came like that when I bought the car). I'm changing over to just the IX DV.

Would I have to have it retune?

 

I wouldn't think so.

 

No.

 

Do you have a pic that u can post up for us of this "compound" setup? Is one valve recirculated and the other VTA? Are they both after the IC? Or, is one plumbed in pre-IC and the other post-IC? Wow, what some people will do!

 

Yeah both is set up on the Uicp. Bought the car how it is. I'll take some pics of it. The stock is recirc and the HKS is VTA.

 

Wow I really wonder what someone was thinking while doing that, I realize it wasn't you its just confusing. Shouldn't need a retune though.
