DIY 06 Mini Cooper S Turbo no boost?

ITs a 07 mini cooper s turbo charged not a 06 sorry. I scanned the car for codes with a generic code reader, and these are the codes Im getting and what they mean according to mini code's, 2nd gen..

P0507- Engine speed too high. IAC system higher then expected.

P1497- Downstream Throttle Air leak

P2177- Fuel trim limit exceeded. System Too lean

Now the car feels like the turbo is not spooling at all. I mean no power what so ever but you do hear a small spool like 1/2 psi and blows off very faint (removed the silencer if that helps). I'm guessing the down stream air leak is the culprit on lost of power and probably throwing the fuel trim off as well. Now what I'm trying to locate Is, what pipe or from what point is the down stream air leak located standing in front of the car or where should I be checking for that? The car also 'hunts' for idle sometimes, It will hold at 2k go back down to idle go 2500k, back to idle from time to time.

Also getting that hissing noise from the P/S near the valve cover on that intake hose the smaller one that leads to the valve cover. Iv searched online and it says it can possibly be a cracked valve cover. The car has 115k if that matters in this situation...
