Simon,
Hmmm......suggestion.....I think it could be the APR exhaust thats restricting the flow. High backpressure can sometimes give you more torque but less highend power due to flow restrictions..... I would try a Miltek dual or something to see if that makes a difference......
I had a new exhaust made for the beemer which increased to 3.5" no cats.....almost gave me another 100bhp as I could wind up the boost...without melting the exhaust. Now running over 700bhp on 95 oct

Expect Jeffs car to be just around the 400 mark.....

However its hard enough to use the power the car has now so I am not sure I would want much more to be honest and the torque is awesome. That said I have seen cars with a lower spec (i.e Dougs) make 400bhpwhich to me doesnt make much sense as my car has no faults on VAG-COM and passed through a MRC healthcheck.
The car does however have an issue with the electrics as the voltmeter normally reads only just over 12v even after a decent run. I think this is due to a faulty voltage regulator which needs to be sorted at some point. Could running low voltage cause a power drop due to weaker spark?
