My boost controll gives me a chatter sound and I hate it

Power fc boost controll, turbosmart 45 external waste 14 psi spring. 3l and 10cm rear.

when this thing comes on boost it makes a disgusting chatter sound threw the wastegate witch I thought was knock Im pretty sure it's the boost controller pulsing. It's also a bit doughy. 

When I turn boost controll off. It spikes to 20psi witch is my target then falls to 15 14. It feels like it has more torque aswell. And Best of all. That crappy chatter sound goes away.

ive thought of some options

am I best to get rid of the boost controll and get a 18psi spring and Mabey bleed off mechanically?

or hook up the  e boost controller so it's not fail safe and just goes to the bottom port and not the top and bleed it of electronically.

or are my settings wrong. Ramp and gain and all that stuff?

My Power FC boost control kit never made any noise. Also, when the boost control is turned off, your boost control should (funnily enough) do nothing. I accidentally turned it off once and hit 27psi before i realised (running 18psi back then)

Sounds like you have another issue. Is it hooked up right?

I'm pretty sure it's hooked up correct. I can double check in the morning. There's a chance the solenoid is round the wrong way.

yes ure rite. When it's turned off it does nothing. And the bottom port of the waste gate still gets boost pressure cause there's a tee piece on the boost controll feed. This is the fail safe rite? 

I feel pretty dumb but this is going back to basics isn't it?

when mine is turned off it hits 20 psi the. Goes back to 14 But that's to be expected isn't it with a "small" 10cm rear turbo housing on a rb30.

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
