Here's where my thinking was coming from. Nothing about forced induction.
Why sell cold air MAFs and why sell MAFs for stock air boxs if they're all the same?
Yeah... That convo is mostly about meters that do well if mounted close to a bend vs. meters that don't. Any vendor selling a meter that is SPECIFICALLY tuned for a CAI is selling snake oil.
I've run all kinds of meters through a slew of different cold air intakes. OEM meters seem to work well in nearly all scenarios, regardless of bend if the stock screen is in place. Others (units without the screens) sometimes have to be "clocked" for them to smooth out. PMAS or Pro-M meters are probably the best on the market.
It's true with nearly all meters that the further you get them away from the bend in the tube, the more stable they are. That's more of a choice of cold air setup than it is of meter.
C&L meters or meters that use sampling tubes tend to have the most issues with turbulence. IMO, the question I ask myself with those kinds of meters are not, "Am I going to have a problem with this setup" it's "What problem am I going to have with this setup and what will I need to do to correct it".
I love Love LOVE Lightning mass air meters. Great meter if you have the means to input your transfer function. Near useless if you don't (unless you own a Lightning).
Not a huge fan of CAIs like the one's that
BBK offers. I prefer CAIs like those offered by Anderson Ford Motorsports. They take those kinds of considerations into account when they design a kit.
That's not to say that the BBK items aren't good. You need to plan ahead to assure smooth air flow over the meter element.
