What is the most powerfull vxr vectra 08 in the country

[S60hsv]

Just wondering as I was told the one I bought used to be but there not sure if it still is I can't see it as it is only 350

A few are ~350bhp from Hardware & Mapping.

One is out there with ~400bhp with the use of Nitrous (I think it is ~340-350bhp without the NOS)

They seem to hit a wall in the mid 300s and there is little development by any UK Tuners to push further with the Vectras 2.8T.
