But then why after hooking it all back together about 2 hours later, it ran fine...even after probably 5 dyno pulls?
Yeah like I said, that MAF on the passenger side bend is not gonna be able to get an accurate reading. Think about it, the flow of air through a bend is not equal across the entire cross section of pipe. There's going to be a gradient of different flows throughout. The MAF only measures flow across it's hot filament which is only a specific point in that cross section. There's no way for it to get an accurate average of the entire cross sectional area.


Here's an example of how flow changes through just 30degrees of bend.

im still wondering why not mount the MAF's before the Split to each TB!
if you did that they would be reading 2x as much flow each.
