all the piss taking aside, maybe clean out your throttle with throttle body cleaner, spray the aac valve as well, give the car a good tune (by that i mean clean the air filter, oil it lightly with air filter oil, check and maybe change plugs, check fuel pressure etc etc) and also are you still using the antrx chip? i never gave you one for j30 i don't believe. could be the reason, that afm has a weird curve and requires a custom chip.
i ran that cai for years and as long as i kept the car tuned, no amount of static electricity, gravity or fucking magnets gave any reduction in power below 3500rpm. i actually calculated the length so the piping would hold as close as possible to 2.4 litres of air, which apparently is good for performance (intake holding same volume as your motor)
also while you're here asking questions, have a think about how many other people are running cai's and never swap them out for summer.
