mechanically how do i set this up? where does it go and do i have to tap? i already have it wired

 

to put it in correctly you need to have 1/8npt threads somewhere on the intake manifold to thread the sensor in

 

prefferably in a high flow area?
or right after the tb?
or does it matter?
and as far as my oem map sensor just plug the hole?
Does the im hhave to be off or can i do it like a egt?

 

just leave the factory map sensor when it is.
as far as where u find a boost source for the wastegate i would recommend the intake manifold somewhere. i drilled, tapped and put a separate fitting in my intake manifold just for the wastegate. works good for me

 

oh and i wouldnt definitely want to do it with the intake manifold off because u dont want those metal shavings in your motor. or if u want to get ballzy u can try pulling the throttle body and drilling close to there on the IM and catch the shavings with a wet rag or something

 

i think ill do that i just got motor bback together would rather not take apart again yet
