Default misfires with Unichip

After installing an Unichip on my car today (MAP based N/A Impreza) I get misfires at high rpm/high speed on all cylinders. Any ideas ?
The cars idles fine and drives normally, only at highway speeds that the misfires occur.
Other mods : CAI - MRT headers - LW crank pulley - HKS Iridium plugs (I have been using these plugs BEFORE the Unichip with no problems)

Thx for any input.

Who tuned your Unichip? I know with the Vishnu Unichips, they would throw a misfire CEL every now and then.
