did you change the valve springs before you started pimpin?

Did it rev past 4100 rpm before the cam change? There is a fuel cut rpm setting in the Global Set Up Parameters window.

You need to make some data logs of what is going on, it could be mechanical or the tune is off.

if you change the xfi from 2.01 to 2.05 I have to change some tables

Yes. You need to go through all the tables and review each carefully and make sure they are what you want. Take your time and study them thoroughly.

No. This isn't the reason.

Fix up the tune in the 2.05 and keep it. Don't go back to 2.01

Then find your RPM and boost problem.

If one fixes the other, then you killed two birds with one stone. But I doubt it will.
