Got the same problem after de-catting mine mate, I think mine needs a remap because I've tried all the normal solutions and nothings worked.

Over boosting and the ecu is cutting the boost it sounds like, remap will fix this.

Check that the bolts from your Manifold to turbo are tight, as well as it could be a blown gasket that may need replacing.
its a triangular shaped gasket that sits between the manifold and turbo, will cause slow boost build up as well as you may not reach your normal boost levels.

Not really no... if its over boosting on a std map then is hardware related and new software won't fix it...

i mean that the mods are causing the turbo to work too well so gets more boost than expected, had this when playing with the actuator, stock map took upto 9psi before cutting it to 4. just a theory, im probably wrong lol
