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 **** welding. Steel mig wire on stainless with the wrong gas

 

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.
