ill give it a shot....10psi?
Speaking from extensive experience? j/k :p

In a blow-through setup, I've found that at 8 psi, the MAF is reading 4.8 Volts, which is getting very close to the maximum 5 Volts.
I'd say 10 psi is actually a very good guess.
Of course this also depends on the turbo.
You could have a turbo boosting 15 psi and flowing very little air or a turbo that will outflow the MAF capabilities at 5 psi.

cause obviously i want to remove my maf. some shops said that the Maf can be removed when i get the extra pressure sensor harness with my e-manage. i figured the e-manage is like a mini aem ems so it should do it no problem. but SP said that i cant remove the maf with the e-manage. any inputs.

damn...only 8psi running blow through? then what happens?
What about if its in front of the turbo?

I may have to make adjustments on my plans then.

Haven't tried it.
I figure the V8 MAF should be able to handle ~20 psi.
At these boost levels, I think it's safer to switch over to speed-density.

I ran low 20's psi through the Lex V8 AFM on my MKIII, made 440 rwhp. I didn't check what the frequency was, so I don't know how much more it can do. This was drawthrough fyi.

~20 psi blowthrough or before the turbo?
