The xc90 was the only model not to get the twinturbo D5 engine. I've been watching the above thread on VOC and it would appear that the polestar map eliminates the delay somewhat.
Depending on the model year, there's also what Don often refers to as the "pincode banditry" meaning it's very difficult to map sone of the newer models. Worth chatting to some of the tuners imo.
The trek to bromsgrove isn't that bad when you consider the fun you'll have on the way home. 476 miles for me last time.
