I've noticed a discrepancy in the recipe of the "Speed Module 3" that may not be intentional.
The Mk3 version of every module costs 5 Advanced Circuits (red cards), 5 Processing Units (blue cards), 1 Alien Artifact, and 5 Mk2 cards.
Except for the Speed module 3. That one costs 4 (four) of the Mk2 cards instead of 5.
The result of this is that for a full set (4) of modules for a Mk3 assembly, you'd need to make 64 Mk1's instead of 80 for this particular type.

Is this intentional?

Pretty sure it's intentional and have been like this for quite some time. I recall a thread about this, maybe you can try searching for it

Edit: Oh, what the heck, I went and searched for it myself: viewtopic.php?t=4734

Ah, alrighty then.
I did try the search function, but didn't get the right terms I guess.
Thanks anyway, means I don't have to feel bad for my cheap cards. (they work miracles when you're low on oil ^^)

Yeah, having seen the thread before certainly gives an advantage in finding it again. For example - I knew I had to search for it in the "not a bug" sub-forum.
That is - I found it by first finding this: viewtopic.php?f=23&t=8167&p=64623
