Not sure if this goes here or in engine manage / tuning

Anyway ever since I bought my evo I noticed (even when I was completely stock) I would get a diluted gas smell or oil smell when I would WOT usually in gears 3-5. I experienced it more so in 4-5 when on the freeway.

Any who now I'm experiencing it more since my ETS intake install through all gears. If I get on it a bit the smell will linger into the car, kinda exhaust fumey like. Any who, any ideas of what this might be? Running rich? Oil in the turbo? Clutch? Once I install my fmic kit I'll be heading over to COBB SoCal for a AP and custom tune and I'll let them know of the issue @ hand.

Would just like to know what the community thinks this maybe and if anyone has experienced the same thing. Car in question is a 2010 GSR 15k miles.
