A couple months ago I experienced the pleasure of my timing belt disintegrating, which of course destroyed my top end. Due to funds instead of putting in a TSI or 2.5 I swapped for the same motor with only 22k. The only mods were intake and DP. Ran great until my DP broke at the turbo flange (looked like a weak thin weld), company sent me a new one which i change out and about a week after started throwing a p2177 code "Bank 1 system too lean off idle". After hours of research and diagnosing i cannot for the life of me find the culprit giving me the trouble code.

The car is an '07 A3 2.0t FSI, BPY Engine code...

Here is what I have tried and where I am at up to this point:
I have since switched back to stock intake and DP.
Replaced MAF, upstream O2 sensor, DV, Coil Packs, Plugs, PCV (new version) & Fuel Filter.
Had it tested for vacuum leaks.
Checked Fuel pressures via Vag-com, all seems to be normal.

Block 003 shows MAF reading air values in normal range. Blocks 15-16 are not showing any misfires. My LTFT in block 32 keeps rising to @ 20% within 10 - 15 miles of highway driving only under about 20% - 30% engine load at @ 2500 - 2900 rpms. The STFT in block 32 stays perfect between -0.5 and 0.8%. Block 33 Lambda fluctuates from 4% to 14% randomly which is indicative of a vacuum leak but cant find one to save my life.

I am stumped and virtually at my wits end. Does anyone have any ideas or experience with this type of situation. I am trying to keep from taking it to the stealership or other service center in my area simply because I don't want a second ***hole, plus the addition of a newborn is diverting the money I could pay them anyway.

Any help or possible theorems would be appreciated!!
