I got the car back now but the power delivery is completely different!!

I'm not heavy on the accelerator at all but when I drove away from the garage I noticed that whereas the power used to be pretty constant it isn't now. Prior to the blown turbo I would hear the turbo spin up and if I put my foot down on the pedal the boost was available and away I went.

Now though, if I accelerate to around 2000rpm in order to get past this rpm I need to definitely apply the foot to the pedal. By this I mean around 3/4 of the way to the floor just for the rpm to increase. The turbo will spin up and then suddenly I feel the boost and the rpm will increase by 1000 plus and I shoot off! Until I get to feel the boost I can only describe this as being like going up a hill in a 1.0L engined car. It's like I'm shouting 'come on, come'on' and feeling like I need to change to a better gear.

My point is that although the turbo does kick in it certainly feels like I have to press the accelerator down much further than before and if I drive along steadily around 2000rpm and just step on the accelerator slightly I'm making no difference at all. It all really happens when I've stuffed the accelerator down by 3/4's. (I'm sure it didn't feel like this at 2000rpm before it went in!). I at least felt a more power through the revs than now.

Any ideas?

I'm going to take it back to the garage and see what they think. Maybe this is how it should be and mine was over boosting or something in the past. Fuel consumption is pretty much as before with less rear end smoke
