Question about boost and wastegates

[eclipytic~ice]

I've been having a little bit of a problem. I don't know how serious it is so I'm asking you guys.

In the first three gears I'm fine with it creating 15 psi, then the wastegate dumps it it 10 then up to 15 again. I assume this is normal. My question though is that in 4th gear it dumps at 10 psi down to 5 or 4. Then I has to come back up again.

If this is just normal for a dsm to do in 4th gear tht would be great but technical advice would be really helpful

You need to run a boost leak test

Now I did replace my sparkplugs gapped to .032 and that seemed to make a slight diffenece to the first three gears and there wate gate dump. But I'll try the boost leak test.

.28? that's huge, .028 ngkbpr6es is what you want. Like ddavisaf said, boost leak test first.
