02 SG Forester Low Boost

[TNHSTI]

Hi Team

 

Recently bought an 02 SG forester XT auto to do a bit off off roading 

 

First thing I notice is it's definitely low on power, the previous owner had been running it on 91 so thats not a great start 

 

Its completely stock and been well serviced, and i pulled the intercooler off last night to check hoses etc and everything looks good

 

Have put a tank of NPD100 octane in it and it seems to be a bit better but it still is down on power

 

What would be the next thing to look at? boost kind of jerks a bit and isnt real smooth

 

AFM maybe? ill try cleaning that with some cleaner and see how that goes 

 

but otherwise be good to have some suggestions

Update, the plugs were very average so in went new ones, but I think the main cause was one of the coils plugs clip was broken so the contacts wouldn't have been contacting properly,

had some spare good ones off a legacy I had that that were lower kms so replaced the coils with them 

 

Drives like the ol girl should now!
