Piggy I can't find a compressor map for my turbo so I have been working off this one for a GT2259. IIRC the air flow is somewhere between 16-21lb/min in the rev range you use so off that I should spend most of the time in the top 2 islands.

James thats not a bad shout, I'll give it a go but IIRC it sounded a little knocky any further forward when we fitted the engine.
