Ok I am getting very frustrated and was wondering if anyone has heard or experienced this before and maybe knows what it is. For starters I have Stillin Gen 3 CAI, and since the installation its gotten worse.

I notice pretty major fluctuations in HP which feel like possibly 30+HP swings. I'll turn on the engine on a cool night and seriously put my *** in my seat for maybe the first 2-8 minutes ... but the same cold night after the engine heats up and the oil is at 200-220 it bogs down to a very noticeable point.

At first i thought it was the CAI actually sucking up hot air from the radiator (still a possible culprit) but that wouldn't support all the supposed gains.

I really want/need to get the car dyno'd but has anyone else heard anything like this? Any possible reasons? its a strange issue. I do live in south fla so cool night is 50's... and thats still rare but its even worse when the temp gets higher.

Thoughts?
