i just recieved my map o2 dump today also with added on wideband bung...i requested have a bung welded at the end of the downpipe but it came in a odd location as you stated...but from what i read from maperformance..they said its best location for accurate reading...im going to see if i can have enough room to run the harness that far out.... one more thing...when you got your o2 dump... how many bolt did it came with? the turbine housing has 5 bolt holes and it came with 3 bolt with same thread pitch and 2 with a more thread pitch.... is that all suppose to be for the turbine housing? so i have to reuse the bolts from the downpipe to cat?

Update:
With the Invidia/Skunk2 combo I had some minor surging issues (Fp Red). With the MAP Integrated O2 Housing/Downpipe, the surging is gone completely. The car drives almost like stock at every point. While in 5th gear, I took the car down to 40mph and then went full throttle. No surging, no BOV issues, nada...the car just slowly accelerated without issue, YES!
Also a note of concern. I was not logging, but after every WOT run I always check my peaks on the Zeitronix (I know, I'm ****) and after one run I noticed a peak boost of 30psi...WTF! Having checked it several times over the last week and half since having the car back, it has never exceeded 25.5psi on the Invidia/Skunk DP combo, not even once. Ill keep the reins on it until I drop the car off for retune on Tuesday, but its something to consider when deciding on going with an O2 dump option without tuning.
