Cold air intake - running rich on de-throttle
 

So the other weekend I welded up a coldside intake pipe and threw a pod filter on the other end of the intercooler, the car will be running like this for the next few weeks.

The car is now running quite rich whenever I reduce throttle. A light reduction will blip into the 13's but if I remove throttle completely it will dip into the 10's.

Using my search powers I assume this is due to the difficulties of pumping cold air and more fuel on the walls?
I assume it's not harmful and simply less fuel economic?
Anyway to tweak this in ms3 to account for cooler air?

Note I also added a GM open air element and applied the correct changes to ms3.

Excuse the pigeon shit welding. Steel mig wire on stainless with the wrong gas :giggle:

has nothing to do with the intake and everything to do with your tune, or more specifically AE and EAE and other fuel stuff

Cheers, just interesting I have never experienced it until I went from hot air intake to cold air. I'll look into it.
