Boost peaked at 1.95 bar but still dropping off to about 1.76 which would suggest the turbo can't handle it or may be need a higher pressure wastegate spring. Ran on Optimax 98, no additives. Added 3 degree of advance in certain areas, also put cam timing to zero, couldn't believe it but my pulleys had moved, I originally set them about 1 1/2 years ago approx to ex -3 and in +1, when I looked yesterday they were ex+1 and in 0! Not good, I'm going to be checking that a bit more often from now on me thinks...Annoying thing was one of the pulley bolts rounded off so I couldn't try retarding the ex cam anymore, I gained around 10bhp at the wheels from putting it back from +1 to 0, I reckon there's another easy 10-15hp from retarding it a couple of degrees so that should see over 600 flywheel me thinks. More power to come though soon...
