As for your first question, I have no idea what you are asking. Can you please rephase and use proper grammer/puncuation? It is part of the forum rules you know
Can you do performance mods? Yes, you can, if you have the proper HVAC tools and experience. If not, then you can send it off to someone like Chilly1 at Xtremesystems.org. He fixes/repairs/upgrades phase change units, and he is a complete professional.
