Sadly no obv difference between stage 2 and std. first of all.

I've just fitted a new turbo on mine and am in the process of running it in.

I fitted new oil and filters to my engine, cranked the engine over for about 30 seconds with the king lead off to get some oil through the turbo and i had the car idling for about 30 minutes after that, just to let it "bed in" slightly.

i've put no miles on it since then, but am going steady for 500 miles as thats what i was told. little, boost in tiny amounts. then i'm getting it setup after the 500 miles.
