I have a really strange boost problem!

The turbo starts spooling normal than boost goes up to 0.9bar and than falls off to 0.25bbar and goes up!

I had a leak in the intercooler piping and solved this problem today!

And the problem is allready here!

I don't have any idea what this could be!

My mods are

Ross pistons 74,5
pauter rods
new bearing and gaskets
metall head gasket
uprated valve springs
2" and 2,5" intercooler piping with samco hoses an t-bold clamps
compled td04l turbo kit
200cpi cat and 2,5" exhaust system
jam ecu
innovate wideband lampda kit
the afrs are ok runs a bit rich
greedy profec b2 boostcontroller

i hope somebody can help me!

I tryed differend settings on the boostcontroller but nothing help!
