Hi experts, have had this problem for as long as i can remember, when reading the codes I always have
17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)
P1297 - 35-00 - -
17545 - Fuel Trim: Bank 1 (Add): System too Rich
P1137 - 35-00 - -
When checking block 032 with vag-com the second reading is -25 showing it is too rich for the system to correct, could this be down to the 225bhp injectors?
Also I have pressure tested the system an found a couple of small leaks which I have sorted but light comes back on after approx a week. When pressure testing anything above 6psi and I had to put something heavy on the oil filler cap to stop it leaking, does this show a problem with the PCV?
This morning I ran a 20mph to red line test logging block 115 and 118, here are the results

As you can see the specified boost jumps instantly to 2070 on acceleration but the actual boost is miles behind, is this why i am getting a boost leak fault code? and should the map demand instant boost like this?
Below is the log for block 118, don't really understand if the duty cycle is showing correctly.
