Hey guys i have a sr20 with a top mount to4e on it. Ever since ive put the top mount on ive been running extremly rich so go it in for a tune yesterday, it has a power fc as its ecu btw. Its had a issue where when i get on it then take my foot of throttle when im in neutral the rpms drop to almost a stall about .5 . I thought the guy tuning it would be able to fix but turns out he cant and doesnt know what the problem is. He thinks its something to do with air flow and his suggestion is to go to a hks fcon which isnt really in my budget . wondering if you guys have any ideas ..

anything is greatly appreciated thanks
