what should i do for a missing link between the throttle body and map sensor there are so many different ways what would be the easiest

NCHATCH

a fish tank check valve is the cheapest and easiet, if its OBD-O, if its OBD-1 you need an actual missing link, BUT

why would you not want your MAP sensor to actually see vacuum and boost, unless you intend on going above 12psi.

i mean if the MAP doesnt see real pressure, how do you expect it to correct for any fuel?

i use to use one, till i found out it was making my tune go to ----

Dr.Boost

A missing link still allows the MAP to see vac, just not boost. Same with the check valves. They are just one-way valves that bleed off positive pressure, but allow vac.

I'm ASSuming he's using an FMU and that's why he needs check valves/missing link. You don't use them with anything else. :1
