Just picked up an sr hatch and i have a few probs that need solving before it becomes my DD

-Under full throttle the engine studders and backfires at around 4 lbs of boost, only when the car is in gear(im leaning towards bad maf)-Speedo and gas gauge do not work-Dash lights up when i press on the brake

I'm new to the sr world, any help would be greatly appreciatedthanks!

A.) Could be potential boost leak(s), vacuum leak(s), MAF could also be the issue.

B.) Wiring gremlins. Get a FSM and go from there.
