there are several options.
1- standalone systems, such as hondata or aem ems. this is the way to go if you can afford it, and a must if you are going big. 3-bar map sensor necessary above 11 psi.
2- vafc hack. apexi VAFC, dsm 450cc injecotrs, resistor pack, stock map sensor up to 11 psi. its a hack, but does the trick on moderate 6-10 psi boost setups.
3- 12:1 FMU, FPR, stock injectors, missing link map bypass checkvalve. Be forewarned, this setup is known to be a piece of shit, but works. I wouldn't use it on anything over 6 psi (12 from the fmu) x 6 = 72 + 46 stock psi fuel pressure = over 100 psi of fuel pressure!!!!! bad bad bad!
