I have 88 mustang 2.3.. I have all 2.3t swap parts necessary to turbo swap.. if I use a supercharger instead of turbo should the vam act similar. Vaccuum is vacuum and how it correlates to boost/fuel trim should be the same? I know turbo is easier but I already have a turbo 79 ford courier running on microsquirt and want something different. The charger I have is an eaton m62 and I am currently making brackets from a 88 ranger smog pump bracket so this will look almost factory...

It's going to be a disappointment once it's done unfortunately, unless you don't have very high expectations. I've seen a handful of these setups built and the supercharger robs a lot of power and also makes so much heat that it kills power. It doesn't help that the SC is inefficient at the sort of boost pressures these engines thrive at.
You'll need a tunable ECU of some sort, not a stock ECU. There is no stock ECU that has a timing table configured for boost just above idle, and the heat of a supercharger with no intercooler.

Thanks for your reply! I have a TC ecu《la3) and volvo(or saab) intercooler which I forgot to mention.. I'm not looking for high hp and dont expect alot, will be going to pimpx ecu eventually but for now if the vam will work with a super I'll give it a try, and if I dont like it it wont be hard to undo and put a turbo on😀

It will "work" but as I said above, the timing will be problematic as the LA3 (or any 2.3T ECU) has timing based on the fact that boost would never be possible below 2300 rpm or so. That's not the case with a SC. So boost at low RPM with too much timing will be problematic.
