Stillen supercharger long term reports

Your MAF may report different voltages after the air has been straightened, though, and those voltages may change differently through the RPM range.

That's why he would have used fuel compensation to even it out.

Or it may be identical, who can say without trying? haha

Edit:
To clarify what I mean, lets say that @ WOT you start at 1.2v around 2k RPM and by redline you're reading 4.6v.

Then you straighten out your airflow and now you're getting 0.9v at 2k RPM and by redline you're at 4.8v. Because the turbulence compressed your delta V over the rev range, and now that the turbulence isn't there, you're getting accurate flow numbers.

But because your tuner set up your fueling tables based on that 1.2v-4.6v spread, you've got inaccurate fueling data throughout the rev range. See what I mean?

(this is all theoretical, numbers picked at random)
