Alright, so I finally got my DE UMP back from Manchovie and she has gone from chump, to champ overnight. She's now a certified BEAST!

Took a stock DE UMP and threw in:
Systema Turbo Motor
Systema Sintered Bushings
Systema Hopup Rubber
Guarder v3 Steel Spring Guide
8.4v 1500mAh Battery (stock was an 8.4v 1050 mAh battery)
Rewired with deans connectors
On the exterior, I have a KA Aimpoint replica and a KA M3 (just realized a day ago that it fits on the rail, so I'll use it for now, but I have a sexier light on the way).
On the way I have a G&G full metal hopup assembly to replace the plastic on in there now, and a Rico Alpha 9 Tactical Light (

She's chronying in the mid to high 330's VERY consistantly. (ten shots in a row were all between 335 and 340fps) and she's pretty darn accurate with that aimpoint on there once I got it dialed in (2 inch groupings at 100ft).
Will update with new pics when the light comes in, but for now, I love her. I've always thought of the UMP as my Eleanor. The gun I've always wanted but would never have, and now I'm glad to say I own one and she's a beast. She truly is my Eleanor.
