since av started a thread thot a mite as well use it wisely. wer on the car can you check if its either a 75ps or 100ps
Do you have discs or drums at the back? Discs = 100hp, drums = 75/80hp.
Seat released an ecu update for the 1.4 due to "lack of power" I'd ask the dealership if yours has had it.
I've done the green filter, slight improvement from standard, providing you take the "flappy bit" out of the engine cover that restricts quite a lot. I've got a Pipercross induction kit on currently, and had better results with that than the green filter. Some of the 1.4'ers have gone with the BMC CDA induction kits. If I hadn't of bothered with the green filter and pipercross in the first place, I would have done the same.
Had a Magnex cat-back system fitted yesterday, increased bore size, no middle box and the back box is essentially straight through as it's for a pd130
I don't think much benefit is going to be achieved from decat.
