Awesome! So with the airbox it kept the gains you had when you completely removed the intake eh? Good stuff!

Yeah it removed the restriction in the intake. It didn’t pick up as much power as i was hoping tho. I think that comes down to the vac airbox. The trumpets are not uniform at all and horrible quality. I think a rep csl box or a nice cai would pick up a little more power

Get the Kassel MAP sensor kit. It's worth it. I just installed it myself
