Probably would put the fuel pump upgrade first but the AP and pump upgrade must be in place prior to the DP

1) AccessPORT + free flowing intake system. The stock ignition advance settings are a little
aggressive, the stock calibration tends to create boost spikes, runs a bit lean on spool up (a bit lean for
the DI Fuel Pressure this car runs), the throttle response is not very linear, etc. We know the stock
intake is very restrictive (too small of a filter and air box for a FI application), relieving inlets
restrictions helps the turbo/engine breath better and respond quicker.
2) CDFP upgrade + Turbo Inlet Hose (TIH). This allows slightly higher boost to be targeted and
allows for the fueling capacity to keep up with the fueling demands. The stock CDFP can only keep up
when 18psi or even less boost is targeted.
3) COBB DP or free flow exhaust system + upgraded BOV ( Downpipe would be here). If this path is chosen, keeping the stock
3-way catalyst is ideal and replacing only one catalyst with a test pipe and CBE will sufficiently
increase VE. The increased exhaust flow will move the detonation threshold up and creates enough VE
to allow for slightly higher boost targets. The stock BOV can hold well up to about 18.5psi, but not
much above that and it tends to bleed off air throughout the RPM range during pulls. You can also
upgrade the CBE exhaust when you do the downpipe installation for an ideal exhaust gas pressure
4) TMIC upgrade (FMIC upgrade for upgraded turbo) + modified fueling system. The stock
TMIC is the most effective configuration that we've seen to date. How Mazda plumbs the TMIC
ducting from the front of the car (high pressure area) through the hood is very effective on the road, but
the additional core size is very helpful at exchanging heat at the higher boost levels on the stock turbo.
You can also install a FMIC to further prevent the heat soaking that a TMIC will see. With a higher
capacity fuel system, you will be able to further benefit from higher base DI Fuel Pressure. With a fuel
feed line that has a slightly larger orifice and with a safety relief valve that releases above 2000+psi, the
fueling system capacity is increases by about 10% (which is very helpful) and with the higher pressure,
the cooling effect of the fuel injection is increased.

This isnt the exact order! But, do the fuel pump upgrade and ap first!!!!
