1 bar 11.5 afr

I think I'm safe but would like to know if things are within safety margins?
My car recently started having a boost creap issue with a turbo change and in third-5th gears I'm going higher boost than the spring weight. I was using stock .8bar boost spring and would usually only see that but now the boost creaps up to 1 bar. AFR is ok (11-11.8/1)
My engine is the 3.0 with 6.5/1 ratio so I feel I'm safe even with this higher boost, safe with engine anyway......car is more insane.
WG holds boost in second to .8bar which is too much but at least it's not 1 bar!

do you have a header?
what about an IC?

have you checked the WG diaphragm? mine was doing strange things kinda like that. i found that the valve guide in my WG was worn out.

1.0bar should be very safe with that C/R if the octane rating is above 90 and you have a good intercooler.

I have an andail Intercooler. I have some crappy OBX headers which I suspect some of the problem to be. I'll look at the wg closer next time I'm down there. Thanks.
