996 3.4 C2 ECU upgrade - anyone got one?

I'm thinking about an ecu upgrade from www.dmsautomotive.com; supposed to give about an extra 20 horses. Just wondering if anyone has had this upgrade and whether they thought it worth the cash?

i had a roock ecu chip put on my 996 c4 that boasts 12-15hp extra. you can feel more pull at lower revs and that was approx £500 from jz machtech at kings langley. don't know the cost of your upgrade but i hear its pretty hard to get much extra out of the 3.4 engine.
