hi all
can anybody please let me know what the standard boost pressure is as mine seems to only be at 1/4 boost on the gauge.
it a 07 st2 with 26,000 on the clock brought from a main dealer.
many thanks

 

When the cars cold, I dont drive too hard, usually wait till its warm. When its warm, mine reaches 3/4 boost in 3rd gear but lower down its about 1/3.

A standard ST will only ever got to about 3/4, only a remaped on will go higher.

 

It should peak to 3/4 then settle at a half. If it isn't doing that it will be your boost solinoid

 

it only gets to 1/4 boost if your foot is hard down at about 6000rpm

 

Boost solenoid mate. About 40 quid.

 

any idea where on the car it is?
