So, can you run the 20psi from where the maf is, or do you have to set from somewhere else?

i think its 5psi from the maf tube and up to 20psi if you hook it up to the throttle body...not sure though

question: do i need to remove the oil cap so i dont blow the cam seals? I read on nasioc that if you dont remove the oil cap the pressure from the boost leak can push out the cam seals? jorge from p&l motorsports said that....here is his guide but he mentions nothing about removing the oil filler cap?!

sorry if i'm ignorant, but i dont think 20 psi would ruin cam seals.

If I had $100 for every person who's been wrong....

I am also looking for the answer as well:

question: do i need to remove the oil cap so i dont blow the cam seals? I read on nasioc that if you dont remove the oil cap the pressure from the boost leak can push out the cam seals? jorge from p&l motorsports said that....here is his guide but he mentions nothing about removing the oil filler cap?!

I am under the impression that if I remove the oil filler cap, all the air will exit right?

errr i took my coupler off my intake and took it into home depot. i couldnt find anything to fit. all they had was 1 1/2'', 2'', 3'' and 4'' caps. i even got a worker to help me and we couldnt find anything. if someone can make sa specific ingredient list of everything needed i think that would help everyone out.

also, the regulator isnt required if the air compressor has one right? i see gauges on some that have "air in tank" and another that says "regulated air". thx yall.
