I'd first get rid of the K&N's, go back to the stock filters, reset the ECU and then let it go through the learning phase of the new setup, then see if things are any better.
I'm no Ferrari guru, but have had similar experiences with K&N's on other MAF based cars, and as a result, I only run K&N's now on MAP based setups.

High mileage, low compression, and missing on a few cylinders.....just like my cars.
