i hear the car runs about 0.8 boost at 3000 rpms and on second turbo about 1.1
i have to be careful how i set my gain and what a set the boost levels to - i was advised 1.4 would be ok but 1.3 would be safer - can anyone with a similar set up help or anyone who knows about this sort of thing open ther gob PLEASE
