what makes a vn +6 more powerful?

[VRV6BT1]

G'day.
Exactly what parts are fitted to a vn hsv +6 to make it more powerful?

Will these parts fit a VR?

Cheers

Do a search mate, i'm sure there is alot of info on here about them, but i think the main one is the chip HSV tune.

Pretty sure it was the chip and might have been something to also do with the exhaust, but not entirely sure.

they have tuned length manifolds from HM , some sort of exhaust and a performance tune

but people on here are doing better tunes than that ive got one in my VP and it makes soooo much difference

mate to get a bit of go get a high flow filter, cai, chipo and extractors.
I had a std vp wagon v6 with cai only that would drag off vr hsv v8's at the lights.
Real shame job.

How difference would the tune be in my +6 to a greenfoam tune for example? I wouldnt imagine it to be drastically different would it?
