MSD Sebring box issues or possible alternatives
I have a 94 miata with a sebring supercharger. The only management it has is a MSD sebring box. Which to my knowledge just varies timing with increase in boost.
The problem: The engine sometimes stumbles. for example; in 5th gear while cruising at 2100rpm. Or sometimes in 1st or 2nd gear if you just mash the gas peddle it will stumble and stutter sort of. I have also noticed that above 2.5k-4k you can step on the gas and the boost gauge will see 5psi but it doesnt seem to really go or pull hard until 5k.
Any thoughts, I tried searching but did not find anything on this. I bought new ngk iridiums to try. And a friend of mine has a fuel and timing power card that I was thinking about trying...I think this might be a better setup but am afriad that it resolution might suck!
any help would be great, Thanks!

To my knowledge it does not have any fuel management, which is why I thought the power card and timing card would be a good idea. However, I have now been debating just getting the Megasquirt PnP...but always have hear medeoqure things about MS...Is the pnp pretty decent?
