Any more info on this.
Im running pretty much the same spec on my sti as shreksta.
this is my graph from a looong time ago. This was before the rcm headers were added so I don't know if its running a little bit more but I doubt it.
I'm think ing I would like to get my hands on a ported vf43, so im interested in what the spool characteristics would be on a 2.0 . All the supporting mods are In place.

This is the graph from my ported vf43 by the porting wizard BIG D and mapped by Martyn j @ Enginetuner.
First graph Graphs show v power -380hp
Second graph-V power + 20% meth
3rd graph- meth map boost profile and power @ wheels.

There is fractional amount more of lag than a 35 but that's if your sat at 2k revs in 4th gear dragging it from the bottom.
With my driving style to be fair I'm never there in the rev range, when driven hard the car is always sat pretty much on the red line so gear changes never drop below 5k at the most.
I use it for mainly track days and it's always sat in the red for 15/20 mins solid so I could be running a gt35 and lag would never be an issue as the revs are so high.
I drove a friends 550hp bug Sti that Enginetuner/Martyn j built and all this talk of lag I was expecting this to be like no boost till 6k them boom 2.1 bar.
The truth of the matter is its nothing like that on the road,
Th driveabiity is amazing, even when it comes on boost and is building up its prob faster than mine then when full boost comes in, f me it takes off like a rocket!
Now that's what I need in my life.
Only thing I find is when on track with the 43 and giving it so much stick in the red line, every gear change you go past the point of when peak boost/torque is etc so hence changing to a bigger turbo at some point that will be back with Martyn j for a re map.
Iain duncan(big d) his porting work on my old vf35 and current vf43 plus his set up makes for an evil fast road/track car that can scare a lot of big cars with the low down response/driveabilry etc.
Martyn's mapping is awesome aswell, last trip to the ring I ran the meth map for 11 laps flat out and the car never missed a beat getting to sub 9 min laps and 11oo miles total journey.
Perfect all round
