The car goes in on the 14th March for a de-cat and a K&N panel
filter then goes in to Andrew Carr in Blackburn on the 19th for
mapping.Did'nt get a full system as i like the noise it makes now.
The car is a 2005 STI PPP,iv'e done some searches on here and
the above figure seems to be what people think it should be ??.
What do you think,Do i need a full system ?????.In my searches
on here people don't believe a System alone gives that much
extra, once it's De-catted,as it is the de-cat that
restricts the air flow.Any advice before i spend my hard earned.
I don't want mega power,but why people think this engine and box
can cope,and keep reliability,i thought i may as well give it a go.

Any advise/Comments would be welcome.

Cheers.

 

see your other thread
Engine wise, its the stongest one subaru have made, the gearbox is also over engineered for the car (unlike previous gearboxes), hence why they can take the power.
