Awesome!
Here it is, enjoy!
This is for the Silicone version but 3.5" ID is 3.5", so the deviations from this to a 3.5" Aluminium intake are <1%.

Also mind that this is for the petrol we have in Europe, so 10% ethanol.
Even if you use some gas that has 0% ethanol the deviations will still be within minimal ranges (<5%).

Indeed I uploaded one for a JBR instead of HTP. I will upload the right one when I get home, however despite the deviation this one should still work because the two intakes are not that different. Usually the difference has to be more than 25% for a MAF cal to make the car shut down after a few seconds, and that is not the case even by far.

Well, that is not the difference you'd see between two different intakes from the same measured ID, more like running a stock intake with the MAF cal of a 3" or running a 3" with the MAF cal of a 3.5. AFR of 9 is more than 35% deviation which is simply impossible in this case.
What MAF calibration were you running prior to this one I uploaded? Maybe you can upload it here so that I can figure out what you have in there.

Here is a HTP 3.5. As you can see these are nearly identical in the idle and low load zone. So you either know you have another intake than you actually have, you pasted it wrong with a huge offset or you have a horrendous leak somewhere because there is absolutely no way in the known universe you have a deviation of nearly 40% between two 3.5" ID intakes, no matter who manufactures them.
