I'm getting a 3 gauge pod soon. I know that fuel pressure will fill one of the holes. So I'm trying to decide what to put in the other two spots. The reason, I want gauges is to better monitor the engine and hopefully catch problems before I have a catastrophic failure. (Again!!!) Right now, other than the BulletProof stuff, everything is stock. I'm going to do gauges, AirDog2, and studs when I put a new motor back in
