Putting everything together and making sure everything is in a row before making the 2+ hr trip up there. I'll be running a 15G Kit on a stock D167y at 8 to 10 psi, looking for 200ish to the wheels. This is the list of everything I have so far:

15G Turbo
Greddy Exhaust Manifold
2.5" Downpipe
Intake arm and filter
IC piping with FMIC and all couplers / Tbolt clamps
3/4 fitting for oil drain
Oil feed is on the way
Oil sandwich plate is on the way
Bov is on the way

OBD2b - OBD1 Jumper
p06 ( already sent off to be chipped )
Boost Gauge
Oil Pressure Gauge

Dsm 450 Bluetops with resistors already wired inline
Walbro 255 is on the way

Now, my questions are:

1) Is there anything that I am missing from the above list that would make the tuning process go smoother?
2) Would you recommend going with a screw in IAT sensor instead of the push in OBD2 type currently on the car? I have seen both setups used..
3) Would you recommend bringing the car with a WB02 already installed?

Thanks in advance..
