[Boost control issue.]

Alright mate, thanks very much for your help

[Boost control issue.]

So I had a look today and it does like the waste gate is getting stuck open, any ideas for a fix? Looking to get a tune soon so need to get this sorted.

I'll give it a go but I'm not sure that's it's the wastegate because when I take out the power from the Greddy unit it makes boost. It's an aftermarket split dump.

when I say everything is in order, I mean the settings look right but the problem is still there.

Yeah it definitely boosts to 14psi, change gear and then no boost. I've set it up properly and had a look at the settings, everything seems in order.

So I've had my R33 for a few months now and I've recently been having boost control issues. I have Greddy profec B Spec II and its acting very strangely. It drives fine and holds boost until it hits peak boost (14psi) then it will no longer make any boost. The display says it's making around 1psi. But then after leaving it for a while it will work fine again, rinse and repeat. Is it the solenoid sticking open? Any help would be great. 

Cheers
