Default need help diagnosing car

did some datalogs with the VAG. I have been getting fluttering from my WoA GFB BPV and am curious if I am getting comp. surge. At the end of the 115 log, the boost spikes up ~200mbar. Is this anything to be worried about? I have also put up a log of block 003. Any comments about either would be appreciated.

I am awaiting the install of a SPEC SIII clutch/LWFW. can anyone post pics of this setup. I am worried that I may have the incorrect flywheel.

Default AWM, ATW and AEB all show different part numbers in the

ETKA but I'd imagine each wheel looks very similar to the others.

Default I dont think the bpv is going to cause a surge that would cause the

boost level to go up, more like the wastegate is shutting as you release the throttle.

Default Was just reading a article last night

that said if your bvp cant move enough air from the system when it opens up that your boost pressure in the tube might increase because of the compressor surge.

How far do you have the screw pushed down? I found that if you move the screw too far down you end up causing the valve to have a shorter throw and does not open up the whole return tube outlet. You might want to remove it and do this test to see if your doing just that.

Default your MAF numbers seem low

I'm assuming the 2001's reach the same lilmit if 214 like my MY2000. I wonder if something in the MAF system is causing you to have boost issue? I would try a TT valve just for the hell of it if you think it's BPV related.

Default I have hit 215 before, albeit in cooler temps..

This log was in 93~100 degree heat. My slipping clutch may also have something to do with it. Can someone let me know what the blocks are to log timing, o2 sensor, and knock sensor. TIA

Default

knock voltage in all 4 cylinders is 026, cylinder 2 will always be the highest.
