Perplexing Split BLM Problem..
Well, I just had my exhaust checked.. no exhaust leak at all. My 02 sensors are brand new.. but I still have a split BLM of about 15-20.. Any ideas??? (I dont beleive my cam is wild enough to be causing it.. but who knows..)

Edit-Worst case scenario is that you have to drill holes... http://www.hashmarks.com/techtips/throttle_body_mod.htm
Keep in mind that this mod worked pretty well with carbs. It worked well with em because the idle transfer slot could get too covered up by the butterflies and if the plate was open too much, you'd have a problem with pulling fuel at idle. The IAC circuit is pretty much revamped in FI apps and the idle mixture screw no longer does the same thing. Worth a read though.
