1988 convertible with a s4 jdm installed

hello. I recently purchased a sweet 88 vert with an s4 jdm turbo in it. Found a bunch of wrong things with it. For starters, he was using the NA pressure sensor, when I believe it should be an N318. There is no FCD installed. I didnt wanna risk detonation, so before I ran it, I drained the fuel, put in 100 octane, a 255lph fuel pump, and installed a boost guage. The computer label is worn off, so Im not even sure its got the right ecu. It also has a brand new HKS 3 inch downpipe, no cat, out to3 inch duals! looks MEAN in back. I fire it up, touch it off, runs and pulls super hard. BUT, its boosting 10- 14 lbs. TOO MUCH in my opinion, obviously with no fcd, and the wrong pressure sensor. My question is, I just purchased an N318 and an N333 ecu from Apex. Without knowing which impedance injectors I have in this jdm engine, Is the N333 ecu the right ecu for the engine?? If it is, I will immeadiately send it to Rtek for stage 1 upgrade. Also, running only 100 octane, will the rtek be enough to support 12 lbs of boost?? THANX!!!!!!!!!!
