TBE and tune - boost issues.

G'day all,

Had a TBE and tune done today on my 2010 STI and whilst on the dyno it refused to make more than 16psi.

Anyone else had a similar issue with their car not making boost. Tuner believes the stock boost controller is the cause of low boost and I will need to upgrade to a mac/grimmspeed to rectify.

Also on the way home I noticed a hissing noise with a metallic tappetytaptap when the car turbo comes on boost. Is this noise normal when going to a TBE? Waste gate flutter?

Cheers.
