Well my bluefin fitted now - car is deffo in EVO realms! There is a noticeable loss of torque low down but not much and certainly not a prob. What you loose low down you more than make up from 3k - 4k onwards - absolute monster for a front wheel drive! You can deffo see why tyres wear out quickly, all that power certainly makes them work and the car does have a noticeable bit of torque steer now - however not as much as you'd expect for 300+hp!
Had a wee blast on the maiden run behind a 997 C4 - he was pushin it but I think not really properly going for it - prob didn't think a Golf would not be that quick - the Golf had plenty of reserve and i have no doubt it would keep up if it were at full chat!
Never seen 14.9 MPG before though!!!!!!
One thing that does make me think mmmmm (apart from how can it be this good for so cheap!) is the fact that it now sounds there is a wee bird under the bonnet as it initially spools up - no doubt the turbo is working harder - anybody know what capacity it runs at (ie what safety factor is left) with 300hp?

? - whats the longevity - Superchips say its fine but......
Russ.C does yours make this noise?
