Well today i finaly got round to fitting my new filter and a cold air feed. The car felt more lively on test drive and the boost gauge seems to move much quicker... The down side though, A slightly naff sound induction noise when pulling from low revs. The best way to explain it would be... like a bloody corsa with a silly filter fitted! The noise changes to a nicer one once the turbo starts to work, But im not sure i can put up with it as i drive alot around local roads and stop start driving.
