and could i feed the IAC metered air thru the same lines as my MAP-sensor is reading?? perhaps add a vacuum reservoir to act as a "shock absorber" and give a more even MAP reading

go speed density. For the map signal, you need a vacuum feed from each port, tied into a common "metering block" and then to the map sensor. You cannot take a vacuum signal from a single port, needs to be from all of them. You also don't want to share that vacuum source with the iac or anything else. They make nice remote mount iac's, but again they need their own separate lines to each port. Think of something like a port-injected nitrous system with the stainless hard lines going to each port in the intake and tieing together in a billet aluminum block. On mine, there were two lines to each port hidden underneath the manifold just like a hidden nitrous kit. Then after the block where they came together we put two bulkhead fittings in the rear of the intake (one for iac and one for map) so there was a connection from the top of the intake. Totally hidden, very clean looking and works perfect.
