yup a vac gauge is useful, but not always easy to read...and i think response is far too slow to tell what is hapening.. most gauges have a small inlet hole (maybe less than 0.5mm) in order to dampen the pulsations.. hint hint 
if you can get a datalogging multimeter and put that on the MAP sensors output, you can get data that way..
what you are loking for is not only the absolute value, but also the variation that occurs with each intake event..
idle = sayy 1200rpm = 20rps = 10 intake events per sec..
the MS can datalog at 15-20 events per second, so you can see the pulsations that are occurring (although not perfectly...but you still get a pretty good idea)
MS runs off a widebands driver ciruit output, ie 0-5V, you can't just plug in a wideband.. there ar emanya round that are getting cheaper.. there was one in US for around $400, Bosch LSU4 included.
narrow band ONLY tells you when you pass thru stoich.. and can only say if you are above or below stoich.. when Ira11y and i tuned my car by SOTP dyno, we got to within 5-10% across the whole rev/MAP range.. so you can do it (we were always rich) but is not always the best way...
you could just ave a fiddle, then chuck it on a dyno once you get the MAP issues sorted... can't be that hard to tune an SAFC or similar...
oh and i'm pretty sure you can use 4AG ECU'S to run spark only (as long as inputs are still there) and use MS as fuel standalone.. but SAFC/jaycar thingy prolly do similar job (except for warmup and accel etc enrichments)
Cya, Stewart
