Looking for upgrade mod

[kurdain]

Quite a while ago I ran across a mod that allows you to spend science to upgrade existing parts, modules, engines, etc. . . 

However for the life of me I can't remember what it was called and searching for obvious terms hasn't resulted in me finding it.

Would anyone know what this mod is off the top of their head?

Thank you,

Is it something like R&D Plus? I remember that there was a mod like that. Crashed my game too much.

I haven't had any trouble with it.

Yes that's it, although I have both tweakscale and fuel switch, wonder how stable it will be.

I have several science mods and I have yet to explore the outer planets and their moons, Urlum, Niedon and Plock, I have everything researched including parts from about 40 other mods, and I have over 10k science with nothing to use it on.

Thought this might be an alternative.

 

Thank you again.
