get another silicone coupler, measure the length of the coupler from the flange onto the pipe. cut half way down the pipe. sock it down with clamps, and you will then be able to clock your maf.

will it help.. idk.. but ****, its worth a try

I turned mine so the MAF sensor was more in line with the air flow, about 10* towards the engine....not sure how yours would be, but it seems like the more I turn it towards the engine, the richer smelling it gets.

I modified my intake so there's no curves in the intake anymore, and no changes. Then i tried unplugging my 02's to make a forced open loop and that didn't change a thing either. I'm going to do the koeo and koer tests now to see what I come up with.
