Had no problems.
Think it is a good car performance could be better for engine size acceleration not the best, but fantastic for the motorway.
I have a vectra 2005 gsi 3.2 you can get by the engine lag and increase hp by having a remap this makes all the difference I had this done also had a full exhaust refit by powerflow with a decat have gone from 207 bhp to 265bhp no more engine lag go, s like a bomb took all the vectra logos of now it's a wolf in sheeps clothing bring on the st220 would luv to make it cry like a baby.
