Jim C. Chip--too lean w/ cone filter???

["Tim Gergen" <m3gizmo@xxxxxxxxxxx>]

I have a 95 M3 w/ euro HFM and Jim C. chip.  I was recently talking to a 
local shop owner who burns his own chip, has his own dyno, etc.  He has 
much experience w/ BMW's and specializes in them.  Upon dropping my car 
off today for a horrible timing chain tensioner noise (I think), he 
looked at my cone filter and said "You know, you are loosing hp with 
that".  I replied that I had the euro HFM and Jim C. chip..(I thought 
the guy was smokin' or something!).  Apparently, he found through dyno 
testing while using a a/f meter, that WITH A CONE FILTER and the euro 
HFM/Jim chip, the car was pretty lean at high rpm.  He says about 14.1 
or so...

Now, I am NO expert on this and post this merely to find out what others 
may have leanered about using a cone filter with the euro hfm.  Or maybe 
even get the master, the shark himself, to address this concern.  I know 
that the Jim C. chip WAS BUILT FOR USE WITH A EURO AIRBOX. So I am in no 
way saying there is a flaw with the chip.  I MODIFIED the setup to run 
with a cone filter, so I only hold myself responsible for any screwups 
with the motor.  I would just like an opinion as to if this guy's 
comments are valid...Feedback?
