Amongst other things the V.3 will have a front entry turbo (90 degree on yours) 440cc injectors (380cc on yours) larger TMIC, probably better internals as V.2's are a grey area, some hove forged pistons, some don't. The version 3 comes with the molybdenum coated low-friction pistons (I think!)
Your V.2 Sti is rated at 275bhp, his 280bhp, would be about the same I think in the real world.
Somebody will be along soon if I have forgotten anything!

Basically, he has a better base car to tune from. For you, tou'd need to upgrade your injectors, fuelling system and TMIC to get over 300bhp safely with an ECU.
He'd just need a fuel pump, fuel pressure reg and the ECU.

I wouldn't agree with that. My STi Ra ver2 makes 308bhp @ 1 Bar with only a full decat exhaust, induction kit, boost controller.
The ver2 also has the advantage of having a TD05 turbo as std.

i have a z4 in my car and it will boost up to about 0.9/1 bar, if i put a electronic boost control on my car will i be able to raise boost just below fuel cut,would it make much differance

A V.2 map sensor only reads to 1.2 bar, this means you would only be able to go to around 1.1 bar.
A cheaper way would be to get a Dawes Device and adjust it according to your boost gauge (if you have one).

The STI 3 has a higher revving stronger engine. His will redline at 8,250 rpm as oppossed to yours at 7,500rpm. The reason mapping is difficult on the version 3 is that they only used that chip for around a year and no-one can be bothered doing all the work mapping them, when they will not have much future demand.
Now we are a few months on, how do the 2 compare, does he beat yours?

1999 IIRC, certainly 2000 on are ECUTek mappable, 1992-1996 ECU's ( std ) can de modified by a Scooby ECU or other Japan / Australia add on chip devices, or some Uk companies like IIRC Scoobyclinic and Powerstation/power engineering can do them too, and 1997 cars are hard to do although again some companies can do those too for a fee...
