Yes, any airflow changes to system will no longer match what’s programmed into ECU. While fuel-map is overly rich and MAP-sensor can be used for slight adjustments, the extra 22-25% more flow than stock will be beyond system’s ability to adjust. You will definitely need PC and lots of dyno-tuning to obtain all extra power possible.
Yes, pod-filters do not filter as cleanly as OEM filter. This has been proven multiple times with studies from fleet operators (trucks and cabs), that switched to K&N filtere as cheaper alternative to OEM filters. Used-oil-analysis shows more silicon (dirt) in oil and higher levels of engine metals.
I use K&N filters on my Porsche race car. While there is a small dyno-measured power-gain (~6hp on 400bhp engine) there is also increased wear and I have to replace rings every 2-3yrs and do complete rebuild every 5-6 yrs due to worn cylinders.
