Ever since I installed my DR725 intercooler I have had some pretty bad bogging/histation when I go WOT. It lasts for around 3-5sec then the car starts pulling, happens again when I go WOT in the next gear.

This is a 2nd, 3rd & 4th gear pull.

Timing and k/c look ok, and boost seems a bit low up top but ok. The only thing I see that would be your problem is your IDC are maxed out pretty much all over the place. This would lead me to believe that you are running too rich and likely the bogging you are feelings. A wideband o2 would be the only way to check that out but other than that I would say that the AVCS could be tuned more aggressively to spool faster and eliminate some bog. An intercooler that large is going to cause lag on the stock turbo so it may be something you need to live with or remove it, or get a larger turbo if tuning is not the problem.
