T8 Boost

Hi boys,

how high can you take to boost up on a T8 with standard Turbo,wastegate etc....

at the moment I`m running 5.5psi base boost & 10.2psi full boost.....

which is standard set from the factory....

0.7Bar= 10.2psi.....

can I run with 1bar=15psi without any problems.......

as for APC/TURBO gauge the needle goes into the red by 3mm under full boost......

I have had a calibrated boost gauge on the car showing 12psi at times which is 0.85Bar right...

but normally the T8 holds 10.2psi(0.7Bar) easy....I only want boost up too 1Bar.......

any ideas please......

who has a T8 & is running 1Bar, remember this is my everyday car.....

many thanks Paul
