Nope, I meant the PDist.
Point was just that if you have a small PDist that's G5 engine-focused, there isn't a huge amount of power available for weapons or systems.
If you size your PDist without considering what internal modules (or weapons) you might eventually fit, you could end-up not having enough power available for them.
It's not a massive problem 'cos you can easily plan a build with Coriolis, and you can always minimise potential problems simply by shutting stuff down until you need it but it is worth considering.
Happened to me when I took my exploration Annie off to the Gnosis.
It had, IIRC, a 4D PDist and I bought and engineered a heap of parts so I could convert it into a combat ship or support ship but it wouldn't fly with all the other kit attached until I replaced the PDist with a 6A.
