This gonna work....?

Looking to up the boost in my 2.5 t1 daily beater. I'm piping in a srt-4 intercooler soon as it shows up. I plan on just maxing the stock mitsu out on boost (18psi). What will I need to do to keep the engine fuel needs satisfied? Will just a set of +20 injectors do? If so, how will the car do during off boost conditions with the bigger injector and a stock pcm calibration?

Thanks

sounds like you will be a new calibrated computer, mayb 3 bar, definately a A/F gauge so you can montior fuel and air ratios.

im not sure that will be enough fuel, you will probly be runnin on the edge im not sure about the plus 20s but it will be very rich and rough at idle without some computer tweaking or rr fpr and you will need to eliminate the cutout point around 14psi,but i would advise to go rich as possible too keep from melting piston ring lands air fuel meters are helpful but your better off with egt or wideband 02. i would add an extra injector also and kick it on at 17psi or just get the plus 40inj and programming and have piece of mind and room to grow
