In performance applications, I strongly recommend people go to an aftermarket ECU. Microsquirt is a very cheap entry level option that is very simple to wire. Tuning can be a little difficult with this ECU, and I generally recommend people stay away from super large injectors with a Microsquirt. Running a Microsquirt will require a switch to a cable driven throttle body. Here is a complete wiring guide to making your own harness. Please note that you must run a 08-09 crank position sensor with any aftermarket ECU, because the older VR sensors don't work well with aftermarket ECUs.

I recommend running ethanol with any boost application, so having an aftermarket ECU allows you to run a flex fuel sensor, and run any blend of gas and ethanol that you want. Additionally Aftermarket ECUs give you features like:
-Boost Cut
-Expanded fuel and spark tables
-Closed loop fueling with a wideband O2 sensor
-Built in boost control
-Launch Control
-Trans Brake Bump Box Control
-Staged Injection
-Built In Dry Nitrous Control
-Traction Control
-The list goes on
If you want more IO and Sequential fuel and Spark Control, I recommend a Goldbox, or MS3pro ECU. They support closed loop VVT control. They are wired very similar to the Microsquirt, but the Fuel and spark outputs will have individual outputs from the ECU rather than sharing outputs. Here is a wiring list for a Goldbox to get you started:
