ok im trying to use some dsm 450's that i bought, but im not sure what all i need. i have my stock resistor box, i have connectors that fit, and iv'e modified where they go into the manifold to make them fit tight, and i also have an SAFC II to lean them out, but i was told i need to "hack" the SAFC II in order to use them? can anyone help?

BTW this is being done to a fully built and sleeved '90 B16A1 with a T3/T4 turbonetics turbo in a crx. im using a walbro 255 pump and tuning with an apex'i SAFC-II. right now im only running 8 psi but im trying to change that with the fuel injectors.

 

Why don't you ditch that hack set-up and get some sort or real fuel managemant such as hondata or uberdata?
If you've invested that much into the motor why risk blowing it with shotty tuning?
