Ordered an AEM 506 Infinity, harness, wideband, and fuel pressure sensor from Moddiction today. Pm'ed him for a quote and he gave me a great price that beat everyone else's by far!
Also ordered all the parts necessary to build a 4" intake with my Ballade 70mm throttle body that just came in the mail. Going to mimic 06Estukay's design and build an airbox for it.

Starting the install of the Infinity and Ballade throttle body.
Got the throttle body on, with a mild port match of the intake manifold. Just used a large half round file to get it pretty close, much better than a 2-3mm solid edge around the entire circumference like the stock one.
Also got the first stage of the intake on, and went for a test drive. Butt dyno says it lost a little power but IAT was about 115 degrees or so. Need to get an airbox built and feed it some cold air. I'm sure it'll gain solid numbers once the ECU is in and tuned

Got some stuff knocked out today. Mounted my SRP pedals, drilled and tapped the fuel rail for the fuel pressure sensor, installed the coolant and oil temp sensors and welded an additional bung in for the AEM wideband. Waiting on an oil pressure sensor adapter and gotta wire all the sensors up and drop the Infinity in.
Perfect fit
Shitty Tig weld crouching with no support, I haven't touched the machine in a long time, but it'll stick.
Little night drive last night

Got tuned by Kenny at Speed factory. Final number were 229whp and 154ft lbs after we made an intake adjustment
2003 AP1 stock engine
AEM Infinity
4" intake with 3" 90 temporarily in place. Car made 220whp with the 4" pipe alone
Ballade 70mm throttle body
Oem header
Cat less Berk 3" exhaust, extra Vibrant resonator.
Kenny said the dip at 5500 is likely due to the 4" to 3" transition being to great. Going to switch the intake from 3" to 3.5" or 3.5" to 4" and see what the car likes best.
On the comparison dyno there was a 12whp difference at 8500 between the 4" intake and adding 18" of 3" pipe, though it did lose 8 hp at 5500 or so.
Final numbers
4" alone vs 18" of 3" piping added. You can see the pointer set at 8500rpm. That 18" of 3" was worth 12whp and 8ft lbs.

When I first got the car running on the basement and gave it a quick road tune to get to the shop, I noticed that my Lambda correction wasn't actually altering the VE map like it should. I roughed the fuel in for a safe trip and once I got down to Speed Factory Kenny confirmed that the Lambda correction isn't working. We loaded a different map that he knew works, checked all the settings etc. This was Black Friday so we just went ahead and tuned the car and I got in touch with AEM today and sent them a data log. Turns out they need the ecu to check it out and repair it. So unfortunately I packed it up and wont be driving the car for a week or so until I get it back. So far they have had awesome customer service though and have been super helpful.

I will once I build it. Materials are in the mail. Also the Infinity references fuel pressure to make sure it supplies the correct amount of fuel via the lambda target and Ve maps, so those values change in real time when the fuel pressure fluctuates instead of just setting the base fuel pressure the and ECU assuming it stays the same. Which after watching my gauge, its typically anywhere between 41-44 psi. So it's more precise. Also the ECU will increase duty cycle in fuel pressure drops dramatically in efforts to save the engine from leaning out too far.
