Hey guys. I got my new MAF housing from Pettit. They sent the housing itself and the filter that goes with it. I don't know if i'm missing something, but i've been trying for the past hour to get the original silicon coupling that attaches to the throttle body to slip over the new housing. Is this what i'm supposed to be doing, or am I supposed to use a different part??

I had one on my shelf that fit. No need to call James.
Ray has changed the routing twice on mine - tells me that he will change it again when he returns to complete some mods.

What do you mean? You mean MAF numbers?
To go to a flash, you should remove the idle bleed hose so that everything is going through the TB.
The MAF tube that Pettit is shipping is a complete piece of junk.
Besides the fact that it is 7% over-size, the taper is too close to the MAF and the inlet, being so soon after the filter, really screws up the flow.
That said, recalibrating the MAF signal to the PCM was a task, but I managed it. The idle ranges (flow under ~8 g/sec max) needed their own, different slope from most of the rest of the response curve.
Basically, what is normally a nice, smooth arc turns into a bit of a hula dance.
But it works.
