Additionally, I hear a rattle when apply slight throttle to bring the car up 200/300 rpms, from 600rpm.

Is this rattle potentially because the car wants to stall? Or should I get it looked at.

Im going to post a video this afternoon as I think my engine is more clicky and rattley, but that may just been paranoia getting to me.

Current mods include K&N intake, Perrin Cat back, Perrin LWCP, Stock tune.

your idle issues are likely exaggerated due installation of non-standard intake and still running stock tune, likely MAF scaling
issues.

The maf sensor is moved close to throttle body with K&N intake likely resulting in turbulance or weird maf readings at low rpm, not sure in K&N intake has air straighter before MAF sensor like stock and Grimspeed intakes have to reduce this
