How do you know it's fuel cut?
Had a similar issue with my car, but it was overboosting an the stock ECU was cutting out the power when it got to 1.5 bar.

boost is just a measurement of back pressure in the intake...what's important is airflow and anytime you improve the volumetric efficiency of the engine with better exhaust and intake mods you're moving more air through the engine.
so it's possible to hit fuel cut without running high boost.

no im supposed to be tuned on saturday...
i turned the boost down to 16 and 17 last night, didnt hit fuel cut at all...then turned it back to 18 19 and it did it again...and its around 70 75 degrees here so im guessing that plays into it...so basically a tune should take care of this?
