Datalogging WGDC and boost leaks

Hey guys, I'm working on a data logging DIY and I need some help. If anyone has a data log of of their WGDCs when they had a boost leak I would greatly appreciate it if you would email me the CSV file( allenrader1@Gmail.com )

Sorry to interrupt the "what intake/exhaust/FMIC/rasp free exhaust should I order?" thread pattern.

quickest and best solution would to be to just send them over to terry. if he says everything is ok, you'll then have your own baseline to work from if future problems arise.

No, i don't have a boost leak and never have. That's the problem. I need logs from a couple people of their WGDCs when they had a boost leak so I can incorporate it into a DIY on data logging and data interpretation.

If pwm maxes out straight away you got a leak.

rader, here are a couple datalogs when I was diagnosing my boost leak. along with WGDC i have boost set point vs. actual boost... and if you want any more info the boost leak was where the charge pipe meets up to the intake manifold.
