It doesnt make sense to smell fuel when you're running lean. Lean = less fuel than stoichiometric. If anything, the HFC is not cleaning out the exhaust fumes as well as the stock cats. You're smelling the fumes as a result fo the HFC, not really because you're lean.

But that doesnt mean you are not running lean.

It's the HFCs cause they don't clean the fumes as well as stock cats

Funny thought I smelled something yesterday and wife mentioned something also. After was drived pretty hard.. No HFC's just mods on sig

could be some left over residue from the manufacturing process that finally burned off due to the excess heat

I would have it checked out. These after market air intake could mess up the map sensor reading and make the car going crazy, to rich, too lean.. no horse power gain but harms.

that's odd...i have the injen cold airs too. i had no enhanced fuel scent come from the car? even with my current exhaust setup, i don't have a significantly strong combustion smell. i guess it's subjective. i noticed from the get go that our cars have more gas fume scent that most other cars...

like i said, subjective?
