Is it normal for a turbo car to sometimes pick up really well when the turbo come's in and sometime's not to?.I've noticed sometimes when i'm just pottering along around town and slightly put my foot down a little bit and the engine when hitting boost seem's really revvy and responsive like it's a different car,then other time's it's just normal as it usually drive's.

Is there a reason for this or is it just typical turbo car character,the car has been mapped and fully de-catted and was wondering if it was down to the map not been perfect or wether something isn't operating perfect.

Anyone have a similar experience or is it just my car.
