An AEM FIC 8 is a good choice if you want to keep your stock ECU and keep everything as close to factory as possible. The FIC is also very easy to tune, and can be a very powerful tuning device in the hands of the right person. It's not expensive either.
With an FIC 8, Supra TT Denso Fuel pump, and bigger injectors you should be good to go.
Stock ECU does a good job at compensating for low boost regardless, from what I've read.
Wiring diagram for AEM FIC 8 for SC400. I got this from MMCTuner who got it from Carlos (both who are running 1uz turbo setups.)

re: ems
thanks alot i am relieved i just picked up a aem f/ic 8 for 300 bucks now one question why do i need to connect to each injector if i will be tuning using rpm maf tps and 02 doesnt the stock ecu control them anyways or is it purely to run aftermarket high impedence injectors instead of stock saturated injectors
