Apexi SAFC II - "Piggyback computer" Lets you modify the air/flow signals to run the car richer/leaner etc. Needed for turbo conversion. Similar to unichip.

FPR - Fuel pressure regulator - Keeps fuel at a constant pressure level?

Apexi RSM w/ G-Sensor - In dash to show you speed/revs/qtr mile times etc. G-Sensor is needed for 1/4 mile times. Look at www.booyamotorsport.com i think he has a pic of his somewhere on the site.

Correct me if I'm wrong, these actually modify the MAF signals into the ECU to trick the ECU into providing the A/F ratio you're after but can only modify signels so much. The Unichip sits after the ECU and checks the signals sent from the ECU. Same result as MAGNA said.

It does regulate the fuel pressure but the rising PFR that is suggested rises the pressure at a higher rate than the stock unit as the factory ECU and FPR causes leaning out and a small lack of responsiveness.
