Well 
Fitted up the new waste gate springs yesterday bought option of 1.3 bar and 1.4 bar Tail springs (combination of different inner and outers). I settled on the lower 1.3bar combo just in case they gave a higher set boost. Along with the new higher power setting I upgraded the specification of the spark plugs and some other details too.
Took the "beast" out for a drive today and the boost went to 1.53 to average of 1.50kg/cm! which is around 1.47 to 1.50bar! or old money 21+psi boost
.......... it pulls like a mother fucker! First 3 2nd gear acceleration runs just torches the rear semi slick tires to 8000rpm, after about 6 or more passes and a few 3rd gear pulls the rear tires got very hot and sticky and could "almost" use all of the extra grunt in 2nd gear (only in straight line though and perfect road surface).... third gear is just stupid and is over in a couple of seconds, its very fast now.
Fuel duty before was around 67% > now 75% same AFR
Power on the Blitz was just under 300rwkw
Peak fuel pressure was 70psi now its around 75psi
EGT peaks have not gone above 890deg C
First cool morning will go out and do a test of the 90-140kmh and also do a 100kmh to 200kmh acceleration test report along with VBOX power graph.
