This solution is often used on intercooler owners starlet, I am still a supporter of the frontal performance. 5injector is a good solution, but here it should be placed after the air temperature sensors
waiting for new measurements on the stand 
The FMIC is the best, This route was just less complicated, cheaper and easier to fit. The 5th injector is after the air temperatur sensor. I can definately feel a difference with the new intercooler.
I had her mapped at my tuner, I wanted a 3rd map for drags, we got the boost up to 1.4bar but the small turbo couldn't hold it and drop back to 1.25bar. The main problem was that the 95 unleaded fuel with octane booster wasn't good enough either, even if we up the boost the power doesn't want to go up so looks like she pulls timing. I need to put in some racing fuel and get the 3rd map mapped again. But not bad power though. The 5th injector did supply the sufficient fuel, but the fuel was just not good enough!
So the 3rd map is not complete will go back with some racing fuel in the tank or stronger octane booster like NF the black bottle.
Map 3(race) vs Map 2(play)
Map 3(race) vs Map 1(everyday)
