diablo sport questions?

Had some questions about tuning and if any one uses it please respond. First what is power enrichment dely, second is it normal for in closed loop to run a high deg. timing then when wot it drops then slowly comes back up, I swear I hear det. but can not see it on the live data, I have my o2s at around .90 mv at wot is that about stoich? Thanks hoping I can get some advise from people that use it>

no you answered my question about the a/f thats what I thought just not sure. Still wondering what the power enrichment dely is. Also Would like to know if any one else feels like they lose power after awhile. Fills good for a bit then starts to feel slow, could be in my mind though> lol. But long term fuel trim is around 4% that seems high. Wish I could really just have it dyno tuned that would be great.
