This is my mates graph, the engine spec iirc is :
SCS Built 400/420
7.6:1 C/R
Ported Cylinder head
BD16 inlet
Stock exhaust
T34.55
Light blues
It wouldn't hold the boost on the rollers due to it being run in 3rd on close gearing but its give you a rough idea of what to expect

Mine made 371.7bhp & 351lb/ft on a Dyno Dynamics RR
Peak boost was only 1.7bar @ 4200rpm dropping to 1.4bar @ the limiter 6700rpm, it holds a bit more boost on the road.
Spec is mild head porting, standard cams, 4x4 inlet manifold, 2wd exhaust manifold, light blues (400s), T34.55, comp 7.8.1

I was going to add that on the day the car ran about 1.7-1.8 bar which goes along with your figures Steve ![Top](https://passionford.com/forum/images/smilies/smile011.gif)
On the road it peaks at 2.2 bar falling to around 1.8-1.9 so I don't think the engine is far off the power figures it made when it was built 7 years ago.

i have the same spec as steve (cossie4i) apart from mine is standard c/r and mine has been live mapped at NMS u do notice more power at the higher rpm (i had a .48 before) it is slighly more laggy but this might be down to the mapping as it did have turbo surge when u was mapping it,mines set at 30psi spike 27psi through mid range tailling to 23psi at 7k
