Default pcm questions

so I think is where this should go , if not let me know , ok so I have a 2000 trans am , 5.3 build turbo and a little spray , I know I need a controller to adjust for the boost and I assume I need one for the spray as well , I was looking at doing a holley efi or megasquirt but I keep reading that I cant use my gauges anymore without having my factory pcm still kinda wired up , what are you guys running , its a street car that will spend some time on the track and in mexico , so I would like to keep the factory cluster , I have spent the last 3 days searching on here trying to get a idea and feel more lost then before , thanks rob

You need HPTuners or EFILive, they each have a custom operating system that supports boost and nitrous, using the GM PCM that came with your car.
