We changed to the newer style maf because of repeatibility and to eliminate the electronic conversion box that was prone to have issues. We now calibrate OEM maf sensors to work with our housing.
I'm not sure what's going on the the hole for the bolt. The factory grommet should fit correctly...
Sorry guys, I've just been made aware of this thread.
I think we need to change our wording in the instructions. We meant to remove the plastic fitting with the clip, not to remove the clip from the fitting. I will get this corrected today.
I don't have any email from the O.P.? our shop number...
You should have no problem just telling them to make the tune for a stock airbox. It will run fine.
Technically they could play with cam timing knowing the intake was less restrictive with the PMAS but I'm not sure if most go that far unless you are spending the whole day on a dyno.
We calibrated a maf to make the JLT work with a stock tune the same way we make one work for ours. The JLT picked up 5WHP over stock on a stock car and ours picked up 16 over the JLT on the same stock car.
I calibrated a maf to test it against the JLT without a tune. Gains should be similar if not a little more with a tune because it will be making more power and therefore be more restrictive. I'm not sure if anybody has done the test with a tune though.
This was on a 13 but the intake kits are...
You will always pick up more power with a good tune on top of our intake. The tune just needs to be for the stock airbox. A tune for the ford racing intake would not work.
We could always make a maf to work with the ford tune for their intake but I don't think they sell the tune without the intake?
