I didn't data log when my car was stock or when I just had a CAI and pulley. I started right before I got my first tune. I wasn't aware of heat issues until after my first tune. I concur that forcing more air through the radiators instead of around them would help. I spent a whole day building templates and fabricating shrouding to force more air through the radiator but I failed. I also believe part of the problem is how to exhaust the air. If I find a cheap used hood I'll put some vents in it.
