Default Question about my UTEC map before I go to water inj.

My current setup is Stg 4 with a VF23, using a custom made map (closed loop). The maps were made for a VF23 with a front mount, I'm still running the stock TMIC so I had to make some changes to get the maps ideal for my car. I've been running these maps for 10k miles now, no problems whatsoever, and its farking fast, at least as far as VF series turbos go. I am ordering my water injection kit next week and was wondering about the open/closed loop thing. Do you think there's any benefit from switching over to open loop or should I go with the "if its not broken, don't change it" theory?

I'm just wondering about the fuel values. My closed loop fuel map values range from -8.8 to -6.7 at WOT. I have another open loop map on my computer that I've never used, but its fuel values range from -5 to -2.3 at WOT, quite a difference between the two. BTW, this is on STI pink injectors.
