Fitted the td04 at the weekend with dan! And it went really well so happy days there.
It's been boosting fine all week at over 30psi no problems but today while traveling home the turbo started loosing psi big time, it's boosts to 5 psi easy but struggles to get over 10 psi. I have a small hole on the side of the tmic where the d seal is but it shouldn't lose all that psi from there.
Has anyone for any ideas?

Lol my small brain has just about worked out that I have a boost leak but the problem is trying to locate it. All the boost leaks iv has in the past is sudden with a massive loss of boost all at once.

I would think the d seal would lose over 30 psi though.........

But think; if you know about a "small hole" somwhere in the intake, 30psi on your TD04 and that small hole doesn't stay small for long.
Good luck with it all

I thought it was weird as it always smokes very badly when it has a boost leak. The d seal is only 2 days old!!

A small leak can be exponential to performance, thats how turbo's work  If you loose 5psi of IMP, you'll loose more than 5+ psi of EMP, causing a huuuuge knock on effect with your performance, it will just tail off. This is where VNT's excel with their manifold pressure management too.

Start it up and spray wd-40 all over the boost pipes, Mine did exactly this (minus the TD04) found out I had a hole underneath the intercooler pipe

Next time your about get me or dan to check your throttle arm isn't set a notch out, should still rev higher than that even with a boost leak.
