it COULD be wired wrong, at least as far as your intermittent tach readings... but that wouldn't explain your other gauges - they have nothing to do with your ignition or the MSD box....
my guess would be on either bad ground to the gauges, or corrosion on the ribbon cable behind them and at the cluster connector

no... if the engine is running fine, I would leave the MSD box alone. your problem is MOST likely your gauges, or the wiring to them. it's a common problem for them to build up corrosion on the backsides and become erratic. Chances are your gauges themselves are fine. remove the gauge clusters and inspect the back of them - the connector where the ribbon cable connects. if you see any white/green powdery residue, clean it well. also the ribbon cable itself sometimes accumulates corrosion - check/clean that too.

you COULD get new gauges.... if you need an "excuse", this could qualify. but unless you WANT to replace all the gauges (can get expensive real quick) I'd try the cleaning first. once you get em clean, put a light coating of dielectric grease on all the connectors.

Like said the MSD shouldn't have any effect on the other gauges. I used to have one and couldn't get the tach working everything I read said no tach filter was needed. I called MSD tech support and they told me it was needed. I ended going with an HEI when I did the fuel injection so never did get the MSD figured out for sure.
