... because it's overboosting like a bastard!

Been to a rolling road session at AMD Technik in Bister today, and got some suprisingly wobbly dynoplots. Martin at AMD (who has a lot of Cossie experience - and seems a thoroughly nice bloke) took it for a quick blast up the road and concluded that either the wastegate actuator or recirculating valve (did I get that right? I forget exactly what he said) was knackered!

Anyone got an idea on costs for getting it sorted?

Cheers!
