I don't know about the tech nerf's so much, I had an Uruz (freighter, 4200) and as soon as I launched, I got the message 'incompatible technology, power reduced to 10% (!!!!!)' and this was with a shield bought from the same place that I bought it, even if it was the heaviest one available, stock civilian turrets, the engine that came with it and so on.
I went back and dismounted my armor upgrade, it wasn't that, so the only thing I can think of is that was my ID..... which for that character is 'Freelancer'.
I don't have that URUZ any more, even tho it looked like it was going to be a blast to fly, simply because with the massive power drop, even keeping the shield charged was causing the power to fall away and forget about any sort of sustained fire......
Edit: looked at the tech chart and noticed that the only ship types that a Freelancer ID won't get some sort of tech nerf on are;
Any other ships owned/made by non-civilian companies come with an instant penalty for a Freelancer ID, which is where the URUZ comes in, the tech chart says FL ID can't have it, being a 'heavy' class Rheinland Civilian ship, this also goes for several other classes of 'heavy' Civilian ship.
