1.6 Turbo help!!

Hey guys! I just got this 1993 Miata with a 1.6 long nose with a CX racing turbo kit with RX7 turbo injectors. I was driving it home and the AFR started reading 7.4 and it would do some kind of limiter at 4500-?? rpms. Then my RPM gauge stopped working and lights started to dim....I know it needs a tune and has a power draw but idk what this is? Any ideas my dudes? Thanks my dudes!! <3

Bad ground, melted 12v positive somewhere, or something else.

What ecu?

Good luck.

its got a megasquirt MS2.
the ground would be causing it to read wrong and make the car act all sluggish and laggy?

If it reads wrong, it won't run right.

From what i'm seeing it could be a bad air/fuel ratio sensor? Its acting like all the symptoms of one going bad, but a bad ground is a probable cause as well. thanks for the help man!
