13 SI RBC,ZDX,RDX, 50 deg Vtc, k tuned exhaust tuning help

Post by stephenbezo »

Hello, I am putting a 50 degree VTC, rbc intake, zdx throttle body, and RDX injectors into my 13 SI. I am using a 3.5'' K tuned CAI and full K tuned exhaust with no cat. Can anyone please help me get it running? I have found where to change injector size, but do I need to do anything else besides change it to be 410 instead of 310? Do I need to start with a fresh MAF tune for the 3.5'' CAI and ZDX throttle body to idle instead of hunting? What kind of sorcery do I need to conjure to use the 50 degree VTC in the 2.4? Any help or information will be greatly appreciated, thanks.

Start with a stick calibration and adjust as needed. Make sure its running in speed density.
